I'll give my wife credit for this much, she pretty much respected the few boundaries that I did lay out (letting our boys know when she would be home, letting me know if she'd be gone past any mealtime, so we could make sure they were fed, no texting or calling OM from inside our home, and if you're going to stay out 'that late' again (2am), don't bother coming home.
I think it's because I confronted her so quickly and so forcefully on her affair, and then exposed it pretty swiftly (about 2-3 weeks) as well. She knew I meant business.
