I don't think I have ever read this many posts on a thread before. I just wanted to comment and tell you I am in awe of you. How incredibly strong and smart you are. I can imagine how difficult this must be and maybe, given your past trauma, there will be times over the coming days or weeks when your resolve may wobble.
So just in case that does happen, I wanted to share something that came out from one of my therapy sessions, which has really helped me.
If your DC grows up and is in this relationship and is subjected to this abuse (& make no mistake, what you have been / are experiencing is a form of abuse) what advice would you give him? How would you help him to stay strong? To remind him that he deserves to be treated with love and respect and care every damn day. To be an equal in a relationship. How would you help him to find absolute joy and happiness in life without it stemming from another individual? Because as a parent, I think I would be heartbroken if my child was unhappy and allowing someone to continue treating them this way.
You clearly care so deeply for people around you - even people that over time no longer are worthy of that from you. Now it's your turn. Channel that energy into yourself - you deserve that more than anything. How lucky your son is to have you. And how lucky that you have made this choice so early in his and your life - so that he gets to see his mum now blossom and love her life.
Change is hard. And I understand that you will grieve what once was, or what might have been. But on one of your responses, you said you missed him. Do you think maybe you miss what he was, or what you had hoped could have been? Because I can't imagine anyone truly misses being called a cunt, being made to feel the way you have been feeling or being so ignored and disrespected.
You are incredible and I hope that in time we will get a life update and hear just how wonderful your life is and how happy you and your son are xx
