1. Sakura does not understand Sasuke:
Sakura has no idea what its like growing up as an orphan, no clue what its like to lose those you care about and love the most. (She compared the loneliness shed feel if he left the village to the loneliness he felt losing his entire family for crying out loud!) She cant understand his pain, she has no similar life experiences she could use to relate to him, and while with a normal person, this wouldnt be that big a deal; Sasuke isnt normal. He only seems to resonate with people who are similar to him and Sakura is almost his complete opposite. Shes too normal for him. XD
Why is this bad?
A lack of understanding means a lack of knowing your partner. If you dont know your partner, how exactly are you supposed to be able to make them happy if you have no clue what makes them happy?
2. Sasuke does not understand Sakura:
Sasuke cant relate to her on anything aside from Team 7 and Naruto. You cant expect Naruto to be the only thing holding their relationship together. Thats way too much of a burden to put on Naruto and Sasuke would sooner just hand her off to Naruto than deal with the burden of trying to use Naruto as a go-between for him and Sakura.
Why is this bad?
Sasuke wouldnt know how to make Sakura happy and hed end up unintentionally hurting her more often than not. Hes a harsh person who doesnt know how to sugar coat anything and he tends to be brutally honest and completely tactless. Which was fine when he didnt care how his words or actions affected others, but if he really does love Sakura, then hurting her like this will eat at him with guilt. Hed have to try and become someone hes not just to try and avoid hurting her as much and that would be really difficult for someone as honest and true to themselves as Sasuke tends to be. Not to mention, trying to force yourself to change like that makes you completely miserable because it puts you at war with yourself. (I know I was every time I tried to change myself for my partner and failed miserably because I couldnt maintain the change and would revert back to my old ways.)
3. Sakura doesnt know how to stand her ground against Sasuke:
She doesnt want to hurt or upset him so she ends up withering and dying at his feet. He brings out the worst of her submissive tendencies which is terrible because it automatically gives Sasuke too much power and control over the relationship. It means he could guilt her into doing just about anything and given how Sasuke tends to be a manipulative control freak, he may unintentionally manipulate Sakura into giving him what he wants without regard for if she, herself, really wanted to do it in the first place or if doing it hurt her in the process.
Why is this bad?
This submissive tendency turns Sakura into a victim of Sasukes impulsiveness. He may hurt her on a whim without even realizing it. Shes not beyond hurting herself to make someone else happy and shes known to hide her pain and suffering from others because she doesnt want them worrying about her. Her submissiveness towards Sasuke means that it would be very hard for her to say no to him on anything for fear of upsetting him or hurting him. (Sasuke has quite the temper and can be very intimidating when hes pissed off)
4. Sasuke is far too strong-willed and stubborn for his own good:
When Sasuke wants something, he pursues it with single-minded stubbornness until he gets it. Hes used to using people to get what he wants so actually having to be considerate of another persons feelings would be difficult for him. Hed want someone who could butt heads with him and argue with him. Hes the type that needs to be constantly challenged, or hell get bored easily. He doesnt want a slave thatll bend to every one of his whims. Thatd be like being in a relationship with yourself and that wouldnt be appealing to him in the least.
Why is this bad?
You cant be submissive towards Sasuke, thats showing weakness and Sasuke looks down on those who are weaker than him. Sasuke has a big personality and a strong will, so you have to match him with an equally big personality and strong will so that you dont end up getting overshadowed by him. You cant ever put yourself below him or he will walk all over you, thats just his nature. Sakura never puts herself above Sasuke, she lacks the self-confidence to do so.
5. Sakura is high maintenance:
Sakura has insecurities and self-confidence issues. She needs someone who is emotionally supportive and encouraging. Sasuke is the opposite of that. Hes not the type to throw compliments your way just to make you feel better about yourself. Hed sooner insult you and force you to face your flaws than compliment you on one of your good points. Some would call this the tough love approach, which wouldnt work on Sakura, shed just think he hated her. She tries to hide her insecurities as best she can, so being forced to face them on a regular basis would really hurt her.
Why is this bad?
When you love someone, their pain is your pain. Hurting them hurts you in the process. Sasuke would be in a situation where hed have to walk on egg shells and really hold himself back lest he upset her by being himself around her. The worst thing in the world is not being able to be yourself around someone. Its like trying to live a lie and it rarely ever works. Even if it does work, you only end up being extremely miserable and hiding your true self from your partner.
6. Sasuke is emotionally retarded/unstable:
Uchihas feel emotions more intensely than anyone else. They literally have to block out their emotions to keep from getting overwhelmed by them. As such, Sasuke is really not in touch with his emotions at all and when he does get emotional, he can easily lose control and become dangerous.
Why is this bad?
Sasuke is prone to overreacting severely even when its completely unwarranted. He could easily hurt Sakura without meaning to and the guilt, pain, and self-hatred spawned by that would destroy him. Sasuke is incredibly prideful about protecting those he loves so being the cause of their pain? He wouldnt be able to handle that. As strongly as he loves Sakura, he would hate himself for hurting her. Hed want to make it up to her and promise her itd never happen again and shed always believe him, every time, even though itd keep happening over and over.
Theyd both be trapped in this endless cycle of hurt/comfort. Shed keep coming back to him because she loves him and wants to believe hed change and stop hurting her. Also, theyd have some good times together, but the bad would certainly out-weigh the good. Sakura would see suffering the bad as worth it for those few precious good times they share together. Thats a textbook abusive relationship.
Hed keep trying to change, and itd work for a while, but every time hed slip back into his old ways and hurt her, hed die a bit more on the inside. Theyd both be suffering and probably unaware of it because the cycle moves too gradually for them to notice it. Also, those few times when theyre truly happy together would deceive both of them into thinking the relationship is actually working when its not.
7. Lack of communication:
Sasuke doesnt talk much and Sakura doesnt really know how to talk to him. They wouldnt be able to be completely open and honest with each other. This would lead to things that need to be said going unsaid for fear of hurting the other person or seeming like youre not satisfied with the relationship.
Why is this bad?
Being able to communicate effectively is extremely important in any relationship, especially a romantic one. If either partner is scared or reluctant to express when the other person hurts them or dissatisfies them, they could end up sending mixed signals and making their partner think everything is fine when its not. You dont want to be in denial about your relationship when there is a huge problem that youre ignoring and really need to talk about. Theres a lot of give and take with relationships, sometimes you have to swallow your pride and admit things that youre not comfortable admitting. Of course you want your partner to think theyre the best lover youve ever had, but you shouldnt have to suffer to maintain that illusion.
While no one likes being made aware of their own shortcomings, sometimes thats the only way to fix a problem; to face it head on, even if it hurts to acknowledge it.
8. Lack of trust:
Sakura finds it very difficult to trust Sasuke. Hes hurt her in the past and has since given her very little reason to think it wont happen again. For the purposes of this essay, Im assuming this relationship was started for the best of reasons and Sasuke had done something to show his remorse and to earn back Sakuras trust. Even so, given my earlier mentions of the hurt/comfort cycle, Sasukes not the only one dying on the inside every time that happens, Sakuras trust and faith in him would take a hit every time as well.
Why is this bad?
Trust is extremely important in any relationship. Some would argue relationships are built on trust. If you dont trust your partner then youll be quick to suspect them and become suspicious of them. Youll start to become paranoid that your partner is cheating even if theyve given you no reason to think so. Lack of trust would also mean lack of being able to let go and be yourself around your partner. If you dont trust them with your insecurities and your vulnerabilities, then theyll never really see the real you. Lack of trust can also have a negative impact on performance in the bedroom. Sex should be about letting go and just feeling but if you cant do that, it makes everything that much more awkward.
9. Sakura is way too hard on herself:
Due to Sakuras insecurities and lack of self-confidence, she will often hide her problems and beat herself up about them in secret. Due to Sakuras inability to communicate effectively with Sasuke, I can see her internalizing any failures in the relationship and blaming herself for them even if theyre not entirely her fault.
Why is this bad?
If you constantly berate yourself for not being able to make your partner happy instead of learning what makes them happy, then youre doomed to fail. You cant allow your partner to put all the blame squarely on you just because youre supposed to be the smart one and more emotionally stable one. That doesnt give your partner license to just shirk or not even acknowledge their share of the blame for them being miserable. They have no right expecting you to just magically make them happy when they, themselves, cant do it. It doesnt work that way.
10. Lack of connection:
Sakura and Sasuke have never been able to connect on any sort of deep, emotional level. Im assuming that would remain true even if they did develop feelings for each other. Feelings do not guarantee a connection just like how feelings alone do not guarantee a healthy and stable relationship. Such a connection would then breed understanding which is another thing this relationship lacks.
Why is this bad?
Sakuras connection to Sasuke has always seemed superficial with her having very little if any reason at all to form a deep emotional bond with him. He certainly didnt have a deep or meaningful bond with her since he so easily severed their bond in part 1. Sakuras the one who pathetically clung to it like a child instead of growing up and learning to let go.
While Sasuke lacks any sort of connection with Sakura, he does have a very strong connection with Naruto. This would cause all kinds of problems in the relationship as Sakura would unwittingly become jealous of the bond him and Naruto share and wonder why she cant have something like that with him. Again, shed probably look at it as a failure on her part and internalize it/blame herself for it while trying to learn from Naruto what his secret is. Naruto wouldnt be able to help her because what he shares with Sasuke isnt something you can teach, its bred from having similar life experiences and just being very similar in general.
