Keep trying WA, or try Respect (It's govt funded, set up for perpetrators
but seeing as they don't often have crises of conscience, the lines are usually clear...
Please get a copy of WHY DOES HE DO THAT by Lundy Bancroft. This will show that it's not to do with you, nothing, none of it. this is HIS choice to abuse you, because he can.
You are right, it will never stop, it will only get worse, and yes escallation could cost you your life.
What options do you have? Do you have children? Can you just pack a bag and get out?
Who owns the place you live in?
If you are in danger, please call the Police on 999.
If no immediate danger, call WA, make an appointment to see your Dr, start creating a paper trail (this is crucial if property/children are involved) If you have to go to court for access etc, you need to prove that he is not suitable to have the same automatic rights as normal people do.
He is NOT normal, he is an abuser, will never change and is choosing to do this to you, because he wants to.
Keep posting, we are here to help.
