DOMESTIC ABUSE

My partner has been abusing me mentally, emotionally, financially and physically for 22 years.  He threatens to kill me when I am asleep and I fear for my every waking moment. Although I have called the police on several occasions (once when he chased me with a knife) the children let him back into the house. Although, he doesn't  hit them they hate him for things he does to me. My mother died when I was five and my father an alcholic so I am isolated and I think if I refused him anything he will hurt me. I tried domestic violence but they said because more recently his violence is more mental and emotional I dont have enough points to qualify for emergency housing. I think because I am more subservient he has got less violent. I just want to have a normal life for myself and my children where we do not have to fear him walking through the door. I would like enough money to move away somewhere he can never find me.
