so fed up

My alcoholic husband is becoming more than i can take, my 18 yr. old wants to punch him and my 12 yr. old wants me to kick him out? i tried to keep this marriage together for thier sake and now they want me to get out of it- go figure. I am really ok with us not being together anymore for my emotional and mental well being, i do realize it is a nessesary evil that needs to be done. I need a job though or a steady source of income to make that happen. I love the man but not who he is now, who he used to be, i hate the man he is now and just want him gone, is that bad? I am pretty sure in time he will get himself arrested again and end up in jail, that is probably how he will leave. It is really sad that he is allowing it to go this far, he was sober for over five years, why put us through hell again? why?
