What exactly does "Going through some stuff... " mean?

So I've been seeing this guy for a few weeks now. He has mentioned before that he wanted to date me or be my boyfriend. I wanted to take things slow, he was okay with that. Well, we act like boyfriend and girlfriend, everyone already thinks we're dating..but when I told him I wanted to be with him too...he said "Well, I'm just going through some stuff right now..and I don't know what I want right now" What exactly does this mean?! We still act like we're together..but we don't have a title...so what gives?
