Hi asm505,
I completely understand your feelings. It's very hard to remain "in love" in an unhealthy relationship. Typically a marriage with an active A is not healthy relationship. AA, Alanon, and many treatment facilities recommend not making any big decisions about your relationship for a year after the start of treatment. I think the reason for this is as we (you and he) start to heal and become healthier our feelings may change. And they may not.
You don't need to make any life altering decisions until you're ready. Sometimes the next best thing to do is nothing at all.
Best of luck to you and your husband!
