Stupid Questions

Hey guys! I really need to rant and I know I can't talk to my boyfriend because he hates it when I down myself but my entire situation right now is super messed up. A little while ago, I mentioned to my boyfriend that I didn't feel healthy and I hated my body. He didn't exactly comment but he didn't brush it off either. I could tell he was thinking about it. Well a few days afterwards, I had gotten drunk and I remember asking him why he thought I was sexy because I wasn't and I didn't understand how a guy like him could be with a girl like me (he is extremely good looking...to the point girls flirt with him in front of me even if we're holding hands or he's got his arm around my waist). I remember him telling me he'd not be upset if I lost weight but he loved me for me and loved me regardless. Well, I think I said something about losing weight for him and he got upset and told me no, he wanted me to do it for me and now whenever I workout or eat healthier or refuse not healthy food, he seems to get upset. I think he thinks that I am still doing it for him but I've been working on this for a while, even before meeting him. I want to be comfortable being his girlfriend but I'm also doing this for me. I'm just frustrated because he doesn't get it lol. I hope he can be a little more comfortable later on.
