First Welcome to PC...

It sounds like he is out of the house? If so to protect yourself you should have a separate maintenance agreement (separation agreement) to protect all that you have...

Separations can be for the purpose of getting back together...or divorcing...

One thought about that...if he wants and you want the marraige to work...it probably will mean separation from him for a good amount of time (Realistically 2 years clean and sober...)...so he can get back on the right track...and you can take care of yourself...
