It sounds like he cares about you, but he is just not sure that he can commit, and is not ready to answer weather he can or can't. It is nice to know that he is honest..alot of guys aren't. i wouldn't force him to answer you, because you might make him say something that he was bot sure of saying. You shoud wait on him to decide, or move on to someone who is willing to be as serious and ready as you are. As someone who suffers from add, I do not think ADD has anything to do with his situation. But you say he has depression, and anxiety attacks...he needs to be on medication to help himself with that. Those things will never get better with out it.
