Thank you for the responses. There is nothing more helpful than to hear from people who have been through all this stuff. I have to say I am a little dissappointed at myself for feeling hurt about the concert incident. I had thought that I had progressed beyond that point.
Seeking answers, your take of the encounter makes so much sense to me. When I read your post it was like you were there. There was a pull with ex toward me during that encounter. The second I acknowledged him and starting talking to him he had a hard time stopping the conversation. He would glance back at her and she whispered something to him and that is when he kissed her. I have a feeling, he had a rough evening that night. At least that is what I am hoping.
The reason I think I have regressed is that I am seeing some progress on ex's part. He has been way kinder, can have a conversation with me without anger, has offered to help me (boat hitch encounter), and even unexpectantly sent me money to pay for my daughter's glasses. I am getting hopeful and I don't think I should be entertaining that thought.
