What do I do?

I don't know what's goin on with my boyfriend lately.he seems so to himself.hes been pushing me away with some of the things he does.i don't know what to do.im having a lot of issues myself..struggling with depression.he don't really help with it,he doesn't really listen to what I have to say about things,he's slowed down on helping around the house.hes just always on his phone and that's all that matters.tells me if I want something around the house to just ask and he'll do it.but I don't like to ask. There's the saying of do it yourself. Well I do that alot.i feel like we're losing touch with eachother. Should I just give him space or should I keep trying to see what's goin on.? I feel I do everything. I try to make him happy but it seems I can't even do that anymore.makes me sad?any ideas?
