You co-own the house and have a mortgage, right? So he has a right to 1/2 the equity. That means he's (reasonably) not going to move out until he has the equity and is off the mortgage. So you need to start the ball rolling on coming to an agreement about how you're going to buy him out, and the timeline. Also the default is 50-50 custody, so not sure why you're assuming that you would get the house due to the kids?
If you guys can't discuss this on your own, then you need to go to a 3rd party. There are lawyers that specialize in collaborative divorce that could help you come to these agreements.
