I think the silence is screaming at you the loudest.... Listen? What is it that you don't hear? You don't hear him fighting to win you back. He only asks if you're leaving. You can't fight for a marriage in which the other person is unwilling to fight for it as well. That is, he has already checked out it seems. It would take the both of you working hard in order to make things right again. I don't see him doing this.
