Wow. Actually I think you played it fairly cool. You resisted ML, which a lot of people wouldn't do, which makes you look strong and also respectful of the process that needs to happen to repair the marriage.
I think the main thing she needed to hear is that you could forgive her. Obviously more has to happen to move forward (transparency, OM, etc), but the fact that you are willing to forgive her so you can at least move in that direction is amazing.
I hope this means she is becoming more stable and seeing things more clearly, and seeing her own actions in a realistic light. That being said...tread carefully.
