I also do not believe the part about if he is a WAH it is over. No two situations are the same, so no one can tell you it is over. You need to try different things and see if any of them work. But make sure you give each thing you try enough time to see ANY changes in him from your changes.
Also, if I were you, I would move right back home. Depending on where you live, the court can say you moving out is abandonment and you could end up with a small settlement.And since you took the children out of state he can say you refused to let him see them. You never know if a divorce is going to get nasty, so even if you think it won't, hope for the best but plan for the worst. I truly hope this does not happen to you, but I think it helps to prepare.
