I loved your last update (most of it) - you sounded so positive! I don't think there are any positives to a broken family, but you can find silver linings if you look hard enough.
What an incredible relief that your H agreed to the custody arrangement you wanted. Whew. Good for you for holding firm, I know how hard it is when you are getting bullied and manipulated.
Hope you find a great house and can get a fresh start. And don't think of this, or yourself, as a failure - please! You are well on your way to being a success story for you and your kids.
