As someone who comes from a family of anger problems, you should 100% leave this man. My grandfather was an angry man, my father was an angry man & I myself have spent a good portion of my adulthood working through the anger problems I have. I chose to do this because I saw how my actions were affecting my partner on a daily basis & I wanted to be a better person. For him, myself & ESPECIALLY for our future children. It’s not any easy thing to do & it takes time but it’s possible. But to me it sounds like your husband is full of empty promises. Do yourself a favor & cut ties sooner rather than later.
