In GOT, love fucks everyone over.
Examples:
Rhagaer loved Lyanna: Both end up dead and start this whole ball rolling.
Robert loved Lyanna: Went to war over nothing, married a woman he never wanted, and got killed over a boar.
LF loved Cat: Jealous fuckboi betrays Ned and tries to get with Cat and when that didn't happen, he took the downgrade with her sister and then tried with her daughter. Still ends up dead over it lol.
I could list every single one. Basically GOT laws state that if you're in love, you will make very bad life decisions and will most likely end up dead. It is known.
