Welcome to SR. You will find a lot of support here, but you will also find honesty. You may not hear what you want to hear, but we will always tell you the truth.
It's obvious that your husband isn't ready to quit drinking. Your situation isn't good, as you know. Your children should not have to live with all that chaos and nastiness. You say you don't want to leave, but you also say you can't live with him either drinking or sober. So, what other options are there? Nothing changes if nothing changes.
