Tired of never knowing what to do anymore

I'm really sorry for this rant but I just don't know what to do. For over 2 months my boyfriend has been acting so hateful towards me. I've asked if he has other interests, if he doesn't want a relationship, if there something going on. I've asked what was going on because I want to help him out of whatever dark place this is but all he ever says is "I don't know what to tell you baby". I just feel so alone. Do I end things? Do I give him space? Do I keep sticking by him? I just don't know anymore but I haven't done anything to or towards him for how he has been treating me and acting towards me so I don't know what's going on.
