I've raised £2000 to Help me to leave my husband

By 8am Christmas morning I had been screamed at, called names, accused of terrible parenting and threatened with having my children taken all because my children left wrapping paper on the floor. My children are 5 and 3 and left to grow the way they are I am in no doubt they will change the world. My husband is NOT a bad father so to speak he is just a husband that struggles and in that struggle sees me as everything that it wrong and everything that has destroyed his life. We have been together 19 years and I am 37 now so I don't remember a life without him. I do not want to take his children from him but I am desperate to be able to provide them with an environment that will be safe and nurturing. I'm scared that if you can not control your anger on Christmas day you might not be able to Control it at all. He has never hurt my children but they hear him when he is out of control. He has held me down and sprayed freezing water in my face to humiliate me and pushed me, laughs at me regularly when I cry. I know people will say just leave but he has control of our family. I sit down for 2 seconds and I am screamed at for being scruffy and disgusting and lazy, I work 3 jobs but the entire care of our children and our house is mine. I know I have to leave but I do not have the money for landlords and lawyers and movers etc... He tells me my chdren would be better off without me, and I have a shock coming this new year. I don't know what that means but I am terrified to think about it. I provide for my family as best I can but I am terrified if I do not ask for help the Co sequences to myself or my family might be irreversible. Please help me
