it sounds like he's trying to guilt you. if someone offered me a meal, i'd say thank you!
can you put more space between him and you? why does he need to be at the house everyday? can he not pack what he needs in the house and take it to his mother's, where he is living?
it doesn't seem a very firm boundary if he can't come home, but he is there everyday.
why not tell him that you need some space for your own recovery and you'll see him only friday night for take-away dinner.
if you want to work on the relationship, perhaps consider a counselor who can mediate...his side of these arguments seem like manipulation to me...
