God help you OP.
You poor pet.
He is so abusive and controlling.
Start telling friends and family the truth.
Start detaching from him.
Start telling your GP about how emotionally abused and controlled that you feel.
Tell the GP of your fear of leaving.
Talk to Women's aid about options you may have.
Start putting money away too.
You are not married which is good.
You need to start planning quietly.
But telling your friends the truth is critical for you to have support.
Get away from him as much as possible.
I hope your contraception is bullet proof, but how you could stomach sex with him is beyond me.
Putting an end to sex might make him look outside the relationship which would be great for you.
But start planning, confiding, saving and detaching.
