Very simple. Ask him why. Ask him why he wants to come to your house on Tues. and Thurs. instead of his place. See what he says. After he tells you, tell him that you are uncomfortable about it because of what he has done and can't trust him and that you'll think about it.
He might throw a tantrum, but don't say anything, just stare at him. He's playing poker with you and poking you to see if there is any give. He's trying to see what he can get away with. Stand your ground based on what you are willing to give and feel comfortable with.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
