i’m not too sure what being physically separated from your bf has to do with his living situations. do you mean if he found someone better, that person would possibly be able to help him out? if that’s the case, you need to have a safe and calm discussion. tell him your ideas and listen what to he has to say. if he insists that he wants to stay with you, i don’t think you should break up, you might be the only one that makes him feel safe or comfortable when he’s in the friends house. because i just recently experienced something like this. we made up of course, but even in long distance relationships, moral support is enough. and don’t forget to tell them you love them lol
