Please don't become a statistic (being beaten or murdered). He is not going to stop terrorizing you and these innocent children.
I agree with the other posters; take your children and leave the house; go to the police or hospital and someone should be able to find a place or shelter.....Do not do it while he is there (he will try to stop you), or if he does get violent do....take the children out of the h ouse;.... Is there a way to make a call to the police when he is asleep or not around? You can tell the police you need to leave and are in fear for yourself and your children; they can come and give you a safe escort.
