After the party, she called to say we should all go to the pool. I could hear the OM in the background. We went to our town center afterwards, and she was trying to text him, while we were there, while I was not looking. I walked up to her and told her I could no longer tolerate her texting him while we were out as a family. She was upset, but she went to the bathroom, I guess to continue. Then she stayed off the phone for the rest of the evening.
