I love her. We're both in our late 20's. We've been together about 1.5 years, and it's VERY serious. I want to stay with her, and really can't see myself with anyone else. She is everything I want: mentally and emotionally healthy (zero mind games), no drama, gives me my space when I need it, not needy but not distant, likes sex, and just good all around. We have a very good relationship.
However, since we started dating, she has stopped exercising as much and started eating more. In fact, she's the type of girl who will eat anything and everything you put in front of her. She used to run 2 or 3 times a week, now she doesn't do it... EVER. She wasn't skinny when we first started dating, but she was definitely still fit and sexy. In the past year, it's really gotten bad. I notice her shirts are all fitting really tight and it almost looks like the chubbiness is trying to break out through the seams (kinda like muffintops?). When she sits, I see the buddha belly form, and her upper half is becoming more and more "barrel-shaped". Overall, it's not looking so pretty.
I noticed I've also been silently resenting her for it, and I hate that I feel that way because I love her so much and my thoughts are mean. I know, I know, if i REALLY loved her I wouldn't care what she looked like. That's bullshit, first of all. But anyway, I think one of the main reasons I'm unhappy is because she seemed to have stopped taking care of herself. It's almost like she doesn't care what I think of her anymore. Or maybe she's so comfortable having such a committed boyfriend, she feels it's safe to let it all go now. It's totally unfair. It's one thing if she has no control of what's happening, but it's another if it's happening because of her own negligence or laziness.
If I were truly shallow, I would've left her by now. I'm writing this because I really need help to stay in this relationship. I want to stay with her. But I also want her to look good. I've tried the whole doing activities together stuff. I've dropped big hints like, "Hey, I think we've both been eating really unhealthy, and we don't exercise as much..." She's not getting it. I've even tried taking up a sport that I know she enjoys, just so I can motivate her to do something. But nothing works. She simply doesn't want to exercise anymore. She doesn't want to run anymore because "it's not fun." Staying in shape takes a lot of work (I exercise 3-5 times per week, so I'm very fit and toned), and she simply doesn't want to do that work.
What can I do? I don't want to be the guy who makes an otherwise UN-selfconscious girl selfconscious. I don't want her to feel bad about herself. I don't want her to think I don't love her. I just want her to take care of herself again. For her and for me. I will never tell her she's fat or unattractive, because she's not. I will never tell her to go exercise if she doesn't want to, because she'll just end up resenting me for it. But I just don't want to have a fat girlfriend, and fat is where she's headed right now. I don't want to be the guy with the fat girlfriend, where everyone says behind his back, "Jeez, why is he dating her?" If she looked this way 1.5 years ago, I don't think I would have started dating her. It's just not my type, and I'm trying very hard to stay attracted.
Please help.
