That's a tough situation, I honestly don't have the answer. I've never been in a relationship where I was in recovery while the other was drinking.
This question is not about the OP's relationship in particular but more of a general question--can a marriage/relationship survive if one is in recovery, the other is an actively using alcoholic?? I feel like if the using one doesn't cross over to the recovery side eventually, the relationship would have to end. At least it would for me.
