Hey guys, I might need a little bit of help here, kind of thorn right now as to what to do.
Back story: I never had a girlfriend until 2 weeks ago (I'm 21, she's 22) I have been obese until a few years ago, and now that I am what some people call skinny ( at around 1.9m in height and less than 60 kgs in weight) I feel great and despise the time I was fat. I went on a date with a Tinder chick who was chubbier than I thought in person and everything seems kind of alien to me and going very very fast.
We hit it off tho, date started like with a hug ( read some pic about this today ), went for a coffee, drank some wine she brought over in the park and some liquor from my home country, eat street food on the footsteps of a building, and bought some beers which we drank while strolling along to get to a karaoke place. Had a great time, made out when we got in the karaoke place (for the first time ever, but didn't feel like a big deal). Combining drinks led to me going to the bathroom 5 minutes into the karaoke place and puking in a urinal. A women started shouted at me and out of panic I started scooping the puke out of the urinal and putting it in the sink. I got banned from the karaoke place so we went out again. I was not feeling very well, so I decided to end the date, but she wanted to come home with me. At home there was a lot of groping, teasing, kissing, snuggling and all of that. That was 2 fridays ago.
We've been seeing eachother EVERY SINGLE DAY since that first date. She told me at some point that she loves me, and I said it back because I would feel bad if I didn't. She messages me telling me she misses me, and I'm the most important thing in her life, and I'm like "yeah, me too" in nicer words. I lost my virginity with her, and again it wasn't a big deal. We had a talk last week about being serious about the relationship, and I was ok with it at the time.
Now my problem is related to both of us: Losing weight made me pretty much not be interested in people that do not take care of their bodies as I do right now. I don't want anyone here to take it personally, but I find it kind of disgusting (it may the porn giving me huge standards, but I wasn't that turned on when I saw her naked). I would be ashamed to show her to my friends, and I feel kind of weird being out with her. A problem I have with her is that I get the feeling she is needy, whenever she feels like it, she calls. I have a very important exam I have to prepare to, and I keep getting bothered with her wanting to come over. It seems like she is way more involved in the relationship than I am, and I'm at a place where I just want to be done with it as now I don't have time for my hobbies (making music, game development, memes). Right now, it looks like she has nothing else of interest to put time in other than me, while I have friends, school, work, hobbies and so on.
I've seen this in the movies and didn't understand it at the time, but I've just heard her father has like liters and liters of fluid in his body from a chronic kidney disease, and has to go on an operation on Monday. I want to end it but would feel bad doing it now seeing how invested she is in me. She is a fun person, we have a lot in common, we laugh a lot together, but it drains me of all my free time and at some points makes my other plans harder to do. What do you guys think, should I try to talk to her about all my issues with her or should I just end it? Can you tell a girl that you don't like her that much because she's fat?
