Need some advice. Things are going well with my new GF, but something happened this weekend that sent me spinning a bit. I went to my older daughter's gymnastics meet with my younger daughter. My XW arrived with a guy. It happened to be the guy that I suspected she was having an EA with before our divorce. I did ask her at the time if there was another guy involved, and of course she said no. My heart trusted her, but there have been numerous red flags before and since--too many to name.

I was surprised. I would have expected that she would have given me a heads up, but she didn't. I can't control that. She barely acknowledged me, didn't introduce us, and sat on the other side of the gym. Up until this point, we have sat together at all of our daughter's events. Afterwards, I told the girls to say goodbye to their Mom, and she could barely look me in the eye.

Later that evening, she sent a text saying she hopes it was okay, and that she'd like to introduce me to her BF. If it wasn't this guy, I might feel better about it. I did tell her that I thought it could have been handled better and that I would let her know when I was going to introduce my GF to the girls. I don't know if I even needed to say that, but I wanted to get that off my chest.

I'd like to get some answers about what really happened, but I know I shouldn't. Water off a duck's back. I just need validation that I should just move on. Even if I asked, she probably still wouldn't be truthful.

What's the best way of handling this? I don't know that I need a formal introduction. The precedence has now been set that we will be two separate groups at our daughter's events.
