<human>: We've been together for 2.5 years and decided to move in together after 1.5 years. Since we've been together I've gained 50lbs and he's always been overweight (actually obese, but that's a morbid term). He has no motivation to change and when I try to help or help myself, he is not helpful nor does he actually support me. He'd rather eat out for every single meal.

Secondly, he owes me over $500 in utilities, but continues to buy things either for himself or me. He's from a well-off family, so he doesn't quite understand how budgeting or anything works. I've tried to help him on this but he just doesn't get it.

All of this has made me change the way I think about him. I get super frustrated very easily with him now and almost annoyed at some of the things he does. I still love him and I want to be with him, but I just can't afford to live how he does and I would be much healthier on my own.

My question is, how can I confront him about this that will not come off as bitchy, selfish, or rude? I'm legitimately concerned for he and I's future together if we cannot even do basic things like eat healthy or even eat in more than twice a week. I'm just concerned and lost. Thanks!

<bot>: My overweight boyfriend spends his money on stupid things, doesn't pay me for bills, and drags me down in his unhealthy habits. How do I break this without breaking his heart or ruining our relationship?
