This man spent years abusing you, no wonder you feel broken.
The problem was not you. His behaviour was completely out of order and extremely abusive in a number of ways.
Please consider going on the Freedom Programme or doing it online (freedomprogramme.co.uk). It's a 12 week course (2hrs per week). It's not therapy, it's just information and you don't have to share anything about yourself or what's happened. You can just listen.
When it was suggested to me I was convinced it did not apply to me and wasn't right, but I decided to go and see. I'm so glad I did. It brought everything I hadn't been able to understand into focus and changed my life.
You don't have to believe my assessment or understand what I mean when I say what he did to you was abuse, but please consider going anyway so you can gather all the information they will give you and you can make your own mind up. What have you got to lose?
It will help protect you from men who behave like this and help you be able to picture a future for yourself again. You've got such a bright future ahead of you now he's gone, you just have to take up the help that is available from Freedom and other organisations.
Everything he did was designed to hurt you, control you, degrade you, isolate you, confuse you, and break you. None of it was your fault. You are not the awful person you feel yourself to be.
I remember how overwhelming it can feel, so just do one thing today. Take one step, and check out the freedomprogramme.co.uk website.
Don't worry about tomorrow's step until tomorrow gets here. One step, one day at a time. You will get through this.
