What can I do? He is going thru like a 'quarterlife crisis' instead of midlife crisis cause hes in his 20s. Get it? LOL srry anyway...he, i guess you can say is depression prone. He has been depressed before when he was younger but while we have been going out he hasn't been in quite a long time. He says it comes and goes. Now it's come back and he is acting different. He is not like himself. When i question him, ask what's wrong he says he doesn't know. He doesn't know about himself, he doesn't know what he wants, all he says is 'I don't know'. We have been having trouble in our relationship recently so i asked 'well do you know if you want to be with me' in which he responds yes..i want you. But then i don't know what it is he's not sure about. Like...life? I am not understanding...Anyhow since i don't really understand the most i can do is be there for him and try to help him. But he doesn't want to talk to anyone about it, not his friends he says, not me, not his parents. He just wants to keep by himself. Since he doesn't want to talk what can i do? It has been causing some MAJOR friction between us. I don't know what he's got to be depressed about..but he is. Seriously what can I do? Just give him space? Or what? I really am at a loss.
