Well we talked. I'm happy with how it went. I was very clear with her about how this event made me feel and if something like this happen again, we would be over. She was remorseful and agreed it was inexcusable.
Post-BD with my ExWW I read alot about the need for forgiveness, both for myself over whatever anger/resentment I had towards my Ex and whatever part I played in the demise of our marriage. BUT I also learned a great deal about the need to forgive those that we love as no relationship can survive long term without that ability. I feel like with this situation we cleared the air, she fully knows my boundary on this type of behavior and what I would do if something happened like this again. With that I want to put this behind us and move forward. For sure I won't forget it and it has impacted my trust in her, but it is not something we can't get passed.
I appreciate everyone's comments, particularly those who agreed with me about the fact that YES I was justified in feeling as I did. As I said above, such concerns seem so very trivial in light of what's transpiring in the world today. Thank you all and pray that everyone stays safe through these days to come.
