Oh lovely you ARE worthy of a place in refuge as are your children… Refuge is for women in your situation. You are clearly afraid of him as he has been violent. I know it is terrifying but have you thought about talking to the police about your fears and hiw you want to leave but due to being fearful of his violence? There are laws in place to protect you as what he is doing is criminal and you deserve the right to be free from abuse and not have to adjust yourself to keep the peace.
Womans Aid will help you with a safety leaving plan and help with refuge, others on here will have experience of that and advise.
YOU are absolutely 💯 worthy ❤️
