Very impressed with your actions and plan! You're doing great!
I usually advocate staying in the marital home, but in your case, I might start looking around for a place, since the house is in his name only and he is not very good with boundaries. It may be difficult for you to stop him from entering the house on a whim, and if you leave, he can't claim that he doesn't have a place to have the kids for visits. But check with your L before doing anything.
