First off, you need to get back your self-esteem. Whether or not you're going to save your M, you need to save yourself first.
I'll be the first to say that your H is an @$$. He likes pushing your buttons, it's obvious. Right now you need to picture him as something you stepped in and have to wipe off your shoe.
He's shown you no respect and for that, you have a right to be pissed. Protect yourself first. In fact, I would make plans to move back home immediately. You know what he's been doing behind your back and it's going to leave your kids and you out in the cold.
Consult a L to know what your rights are right away. He will start to do more underhanded things, so you want to make sure your assets are protected. You don't want him to start emptying out your savings without you knowing.
We are all here to help you whatever your decision may be, but what you must remember is to not feel guilty about what you're doing.
He is the one causing all of this. Not you. He's going to start pushing your buttons more than ever, just to get a reaction, but don't give in.
When my W was at that stage, I learned to picture her like one of those homeless people who ramble nonsense. I learned to here blah blah blah when she was at her worst and it didn't hut.
You can do it.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
