You sound like you're pretty sure there will be a "next round of drama".
It's so important to use these quiet times wisely. It sounds like that's what you're doing. I found that I was really able to put my husband's last batch of sobriety to good use. It lasted for about six months. I used that peaceful time to work on myself, all the while knowing (in the back of my mind) that it wasn't going to last. When he started drinking again I was ready to move forward. No drama, just calm reality.
But I'm curious, Merry, are you afraid that you'll want to be sucked into the drama? Are you afraid that if you hear about his problems you're going to want to jump in and fix them for him, or are you worried that other people are going to pull you into it?
