Sometimes, those kinds of mixed signals are a way to sort of keep another person off-balance, so they cannot quite see the relationship clearly. I'm not saying it is a conscious thing, but I have seen that kind of behavior a lot when one person in a relationship wants to keep the other person "on the hook", so to speak.

I would certainly not recommend moving in with a man you are not sure of, and if he is just starting therapy, you may find that he goes through some rather big changes along the way. The only way for you to know if it is too late for you is to look in your own heart. Have all of the problems 'til now eroded your trust to the point where he can't get it back? If not, and if you are willing to give him the time to work things out in therapy, then maybe there is still a chance for you.

Good luck.
