I would tell him it is dis-respectful to you to keep that stuff around. He can't keep both that stuff and you. If the shoe were on the other foot, would he put up with it?
He is going to counseling, that seems like a positive, he admits his own faults, that is a positive.
You feel like roommates...hmmm why does he say that? That one sounds like you have a part in creating that feeling, no?
