How are you Chicki! We're pulling for you. If your H is going to have tantrums, and threatening ones at that, then you're going to have to gather every once of calm you have and live inside it as though it were a bubble. It's time to leave all the fights--all the words--behind, because fights and words aren't working for you. Anger isn't working. Bitterness isn't working. You're going to have to pretend that you don't feel these emotions, even though it's totally natural to feel anger and bitterness and despair. Doing what comes totally naturally just isn't working. I think that you're going to have to present yourself to your H in a totally different light, and stick with this new, calmer, quieter person, day after day.
And it won't be easy. But, bless you, girl, I know you can do it!
