No wonder you don't have a sex life with your partner. He has abused you. He knows this and so do you and thats enough to kill a sex life.
I'm so proud of you for deciding to leave him. I know how hard it can be and just want you to know that you are doing the right thing and that you are a very strong woman. I would go and seek some therapy for all the damage he has done to you. You'll prob need this to be able to trust again.
You don't deserve someone that abuses you and what more someone that doesn't respect you and who has been unfaithful. You deserve a lot more than this and there are good people in the world and i am sure you will find that someone to make you laugh and whom you feel safe with and truely loved by.
The best of luck for your promising future darl. I truely mean this.
xoxo
