<human>: I'm 24 (f) and my boyfriend is 25. We've been together for 4 years. 

My boyfriend grew up as being "the chubby kid" and has always had insecurities about his weight. When we met he was in the best shape of his life. About 2 or 3 years into the relationship, he gained probably 10-15 pounds. Ever since then he has been almost obsessed with trying to lose the weight.

Let me just say that I think he looks great. He's got a little extra around his sides but I like that -  and I tell him all the time. It's what I like.  

We don't live together but we spend most nights together and every morning he stands and stares at himself in the mirror, looking upset or annoyed, when he thinks I'm not looking. He bought this expensive scale online that he couldn't afford because he thought it would motivate him to lose the weight. 

I desperately want to help but there is only so much I can do. I encourage him when he mentions he'd like to go do something active, I comfort him when he's vocalizing how shitty he feels about him self. I feel like he resents me because I'm one of those people who can be less strict with their diet and not worry about gaining too much weight. 

His confidence is gone and that's a big part of why I was attracted to him in the first place. I feel horrible saying something like that because I know how shitty he feels but this thing effects me, too and it's been so long that we've been dealing with this that I don't know how much longer I hang around. Confidence is a trait that is important to me in a mate and he just doesn't have it anymore. It's not the weight that is making me less attracted to him -  it's his overall attitude about it and lack of confidence.

Is there anything I can do? I just want to fix this and move forward. If anyone can provide me some insight who has dealt with this sort of thing before, I'd really appreciate it. I'm kind of having a hard time understanding why all this is such a big deal to him. 

Thanks.

Can you condense the text into a few key points?
