I agree with Anvil
He's not adding, but sure taking a lot.
This kind of tension is really harmful to children
and isn't good for either one of you.
He's being enabled to not take care of himself or anything,
and you resent getting stuck with the work and the bill
Meanwhile, kids are living in an atmosphere of anger and dysfunction.
Maybe he needs to get into sober living and give you some space
so you can both work on recovery?
This situation doesn't seem like one you can keep it up much longer. . .
