Is your husband drinking? It sounds awful, you say you’re okay but probably not. Kids to turn on you, violent husband..... get a plan and get out. Those kids are old enough, and that husband can throw remotes by himself. I feel they are kicking you while you’re down. You don’t need that abuse. Even if you messed up badly, you are trying to get better. You need love and support right now. Can you go stay with family, non drinking preferably? You must take care of you right now. Oh and the husband bringing the kids into an argument like that was a low blow and sick on his part.
