My ex boyfriend is at my house and I am confused.

He is at my house because we are waiting for results on my dogs surgery. We are watching a movie and I dont know why but I really want to hug and kiss him. We haven't talked in days and fought a lot in the relationship. I dont want to get back together but having him so close is driving me crazy. Should I make a move or wait if he wants to? Or not do anything at all and not give in?
