Hey there and welcome I've been in a relationship before where I seemed to be the only one pulling the weight and taking the responsibility for making things work. After talking to the guy 4 or 5 times about the same thing, you have a right to issue and ultimatum (and this is coming from an anti-ultimatum kind of girl). The thing is this-- he's living his own life from your apartment without much regard for your needs. It sounds to me (and I'm SO willing to admit that I could be wrong) that he isn't ready to take responsibility for himself, much less take into account another person's feelings. Hopefully, if you take the above advice and tell him that you guys need your own, separate living space he'll wise up and have some time to grow up. Right now, it sounds like his Mom has always bailed him out in the past, so he lived off her for a while, and now he's doing the same to you-- in my heart I really think that if you force him to live for himself for a while, if he really wants to meet you halfway and continue the relationship he'll be better able to make that commitment to you and your needs.
