The Boyfriend with NO Complaints

Should I be concerned that the boyfriend I’ve known for 4-5 years now have no complaints about me and our relationship? He told me in a myspace message [it was a while back like way before I moved in and I barely got to see him] that he has a hard time expressing himself, mostly about his life. He basically said he don’t want to make his problems mine so he tries to avoid that as much as possible. Anyway, I’m just curious as to why I don’t get feedback on how a good or bad of a girlfriend I am. He can’t even tell me what he likes about me or why he loves me. [He don't even say those 3 words any more].

I’m starting to believe that moving in was a bad idea. There’s no time to miss each other being that me and him are both unemployed at the moment. So we’re always seeing each other. We eat, sleep, play and everything else together. But no matter how many arguments we get into or opportunities he have to tell me about me he don’t. Yes, I’ve tried asking him but he just changes the subject so I leave it alone. Maybe its just me.
