It's not you, but him. You are trying to have logical and rational conversations w/this man and he's not getting it. I know you want to explain the therapy sessions, but he doesn't care or want to hear about them, so stop doing it unless he asks you about them. As for him not trusting you...it's projection at its finest. It's not you he doesn't trust, but himself.

The best thing you can do is keep the focus on you and your children and leave your h to his own mess. There's nothing you can do to fix him because you didn't break him. He has to be the one to hit his "bottom" and figure things out.

Protect yourself, your children and your finances/assets. If the conversations become heated, cut them short and walk away.

Again, it's not you.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
