The general consensus was that you don't owe your roommate anything. Maybe later down the road if you become friends, or if they straight up ask, but you don't have to feel obligated to tell them. I was going to tell mine first thing but changed my mind to wait. If it comes up, I'll be honest, but I don't want to give him a preconception from the start before he gets to know me.
