Welcome! You are not alone in this one bit. There are many here who have been going through just what you describe with children, a home, a job, and the rest to contend with. I am so sorry for the reason that you are here, but delighted you have found us.
Please do some reading and reconnect with yourself and what you really want in your heart going forward. He is the only one who can decide to seek sobriety. This is his path to walk, but you do not have to be around for the carnage to take place nor do your children. He knows what sobriety is and how to get there. He does not need you to be dragged by him to reach it no matter what he says. Let professional detox him. Let him stay away until he has gotten his act together.
You just focus on what you can do for yourself and your children to keep out of his distructive spiral.
Al-Anon is great advice. The stickies at the top of this forum with suggested reading and helpul info is also good starting point.
We are here. Keep posting!
