She doesn't have "Ricky" over when your daughter is there, does she? If so, I'd put my foot down about that. It is entirely inappropriate since you are still not divorced.
Secondly, you at least were detached, but I wouldn't have said, "cool", I would have said, "As long as it doesn't affect Abby or that they are staying over when Abby is there, I don't want to hear about your social life." Set a firm boundary. Your wife shouldn't get to share her cheating excursions with you.
I applaud your previously stated goals. Good luck. Any time you feel like slipping up, or feel like you need to hear from your wife, just remember that this is the same woman that promised to forsake all others until death. She's not a great catch at the moment...you certainly wouldn't choose her based on her high moral standards. She should be crawling through broken glass to you, not the other way around. You are the catch.
