I feel I acted a bit passive aggressive with my action last night and can only wonder if that pushed her to reach out to OM.
Was it P/A? Yes. Was is justification for her running back to OM? Oh hell no. It was a minor jab and she could have said "hey that felt like an attack and it hurt me" and you could have said "I can see why you felt that way, I apologize." That's how adults would handle that. But she's not an adult, she's a lying cheater and acting like a rebellious teenager. Keep working on that detachment!
