Many here say to break up, you're not compatible. Acting like sex is the deciding factor in a relationship. I get what you are going through and him as well. But the relationship is simply not being handled properly. Instead of expecting him to understand, and instead of you expecting to be sexually available, you both need to talk. When he's sober, not horney and ornary. Like you said, it was a drunk time and neither of you were appreciative of the situation.

I get that it looks like a deal breaker, but at 20, a bad smell can be a deal breaker. I'm 50, was a full on hedonist in my 20's, sucking cock and sleeping with married women, But a nerd, so had like 3 week moments where sex was never on my mind.

I'm not the same person with my parents, then I am with my best friend, nor with the boy of the night. But if I'm going to commit to something, I know to have a goal and work, hard, to keep that ball in the air.

You are exhausting yourself with work and school, and that is admirable from a parents & similar friends perspective, so you should have lots of support, though I don't know your whole deal, are you alone without him? You did NOT connect with him because of your shared goals, so what do you two connect in. I suspect he loves your stability, responsibility and I suspect you like taking care of him 80% of the time. But he still thinks it's his right, not a privilege, they say the heart grows fonder...

You admit eating is not only pleasurable, but consoling. You are getting "fat" because of it, and he still wants to have sex with you. You are ignorant here. 1, you aren't getting fat you are getting support, 2, he wants your tubby bottom, 3 you are happy with your situation, but the mirror is a reminder to you of your failures. This is NOT a fat issue, but a self impulse and consequence issue. You regret taking time to self sooth, but dont let him in to help. You know sex is another method to self sooth, but you avoid it, why? look in the mirror and see the girl, not the "issues", but the girl who's sad because she isnt supported.

So, marry him, dump his ass, become his sex slave, or make him yours, it doesnt matter. You fell alone in this, and the next choice is yours, do you want to be left alone? Or do you want him to be there, learning and understanding with you? oddly enough, you are not alone except in that head of yours. You came here for support, and I see the rash answers, now step up, and have that hard discussion. Personally, I suggest a chastity cage for him.
