Hi Sara, I just caught up with that thread, I didn't notice you started a new one.
I totally agree that you tried everything and beyond to salvage your marriage with a very uncooperative WH. You need peace, your home should be your sanctuary. May be him being by himself withou you caring for everything in this life (house, kids, groceries, cleaning, laundry...) might show him down the road what a great woman and wife you are.
He needs a wake up call, believe me some men don't realize how much work and attention 3 young kids need on a daily basis, even if he helped you at home.
Do you think that his burst of anger might come that he realized that you are really done and you are ready to move on. He lost his control/power on you, you are no longer a wife he can manipulate with a few nice words but actually you are requiring now actions and enforcing boundaries. You are no longer afraid of confronting him even if it means to lose him.
Bigs hugs, my thoughts are with you, you are strong, you deserve being respected.
