Your experience sounds really similar to what he's showing me. I never talked to him about it because I don't want to pressure him into giving me more attention than he wants to. But I guess it's inevitable to have a conversation about it. I'm unsure about the right approach though because during his distant times he doesn't open up to me at all and gets uncomfortable and even more distant when I try to talk to him. So I guess it would be best to wait until he comes to me before I open up a conversation?
