I clicked this thread and went and read the first.
Coming back to this one, I'm so sorry to see that he's got inside your head.
He physically hurts you
He manipulates you
He gaslights you
He controls you
He puts you down
He isolates you
He doesn't believe you know your own mind
He doesn't believe in you or your dreams
He doesn't love you
He doesn't even like you
All these strangers on the internet care far more for you than the man you married. We see your worth. We see the life you deserve and could have.
I second the person who said our kids needs teachers like you. People who can empathise with them, believe in them, and inspire them to be themselves, and stand up for themselves.
But to do that for them, you first need to do this for yourself. Whatever it takes. Even if you have to walk away with nothing. You said it yourself, people leave with far less.
I don't know what's keeping you from returning. But from the point of view of your physical safety, I'm really glad you confided in your mum about your plans.
