I also don't believe she is using that as an excuse to maybe try again. Maybe she just wants you to make things easier for her, by asking your S to behave better for her. Which if he is being disobedient or disrespectful, you should tell him he needs to act right. However, if he is using Xbox as a distraction when om is in the house, if she is allowing him to play video games to keep him quiet and out of the way, then that is for her to deal with. Your S seems bright enough to know the difference. She should not use you to make things easier with om. And her getting you to babysit (yes, I know they are your kids) while she goes for a night on the town, is just plain using you. I would not be so available for her on those occasions if I were you. Talk about being walked on.
