One of the first steps that many people here are forced to do, in self-preservation, is to separate finances. Is she earning an income? Where does your rent come from? Does she have free access to spend anything and everything she wants on booze? And if so, why?
If you are able - and can find it in yourself - you've got to stop this speeding train or you will all end up on the streets. She should NOT be permitted to drink you into poverty. Protecting your bank account used for living expenses may be necessary.
You have some hard decisions ahead, newfather. I fear that without a self-protective stance soon, (even if it makes her mad) you could lose everything you've worked hard to build for yourself and your children.
This is the harsh side of recovery.......doing what it takes to protect yourself against alcoholism even though you still love the alcoholic. Sending you luck and strength to think outside the box and do what's right. This will not get better on its own.
