I just found out that my x's live in boyfriend took my daughter took to a Father/Daughter dance. This was done on a weekend that I do not have my children without my knowledge or consent. I found out from my daughter after the fact and subsequently got upset, leaving an awkward emotional situation the two of us. For context she is 9, and had no idea that this would hurt my feelings. I have no issue with the x's boyfriend trying to do something nice with my children to create a bond, but I felt this was truly over the line. Am I being selfish? I know I was intentionally left in the dark about this, and now I am outraged with the communication with my x getting derogatory. She doesn't get it and she never will, but I am not going to sit back and not let her know that this was disrespectful. That fact that this dude gets to see my own daughter every day, and thinks he then can steal special moments like that is pretty hard for me to swallow. Any thoughts or advice would be helpful.
