Your WH could be MLC as well as addicted and compulsive.
Some addicts are just that addicted and compulsive.
You will have to let him fall and be careful that he doesn't take you with him.
My WH is a compulsive, gambling alcohol, OW, spending and oh yes abusing.
That is what I see for a codependent.
You DB for you and let WH fall. By all means read my threads and known unless you can set boundaries then it's a bumpy ride.
There is nothing you can do but detach. It is a saviour in a sitch with an addict.
Remember that you are dealing with your WH addiction and not with him. There are other sitches here with addiction and it is the most difficult of all. Addicts may abstain to please you to hold on to you.
My recommendation is to allow WH to hit bottom and if you can AA for him for life.
The other aspect of this is to discover if you are codependent, if so you will need all your energy for you.
