"She would just say "I can't help that he decided to attend the same event WE did, what do you want me to do, tell the kids, 'sorry we have to go home.'"
When she left, did you make it clear to her that she was not to be in contact with the OM or that the kids couldn't? If so, then I would ask her about it. If you laid down the boundary, it has to be addressed.
It's like a teenager sneaking out to go out. If you ignore it, she thinks she will have gotten away with it. Kindly remind her that you are the children's father and do not want them to be where the OM is. If he is to be in a public gathering, she is to tell you so that there is full transparency. Just say that she still has to earn back your trust.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
