IC is an excellent idea. I recommend someone who does EMDR.
I think after a while many fWPs become complacent and can start taking the relationship for granted. I don't think most understand that the betrayal is not something the BP will ever fully get over. We just learn to live with it. fWPs seem to be able to fully put it behind them. They don't think about it. It only affects their lives as it affects their BP.
I had an incident with my H a year or so ago after being in R for 9 or 10 years. A young woman at his gym contacted me and asked what my H would like for his birthday. I didn't know this woman at all. I had never met her or anyone else at his gym.
I asked my H about it and found out that the coach would partner my H with her almost all the time. They both like to compete and my H is really good at pushing and encouraging people. This woman had come to rely on my H for that support and wanted to show her appreciation on his birthday with a little celebration at the gym. He said they do it for everyone. The problem was that this woman was just another member, not an employee of the gym, and she was the one doing everything for my H.
I told my H it was too much and had to stop. I insisted he tell the coaches he wouldn't partner with her or any woman anymore. He immediately complied with my wishes.
We talked about it for a few days. He said he thought we were at a good enough point that it would be ok. I told him we would never be that ok again. He gave up any right to have any kind of one on one relationship with any other woman while still married to me when he cheated.
I knew he wasn't cheating again or trying to cheat or probably even flirting. He's always been clueless. I think it just didn't occur to him that I would have a problem with it.
(To give some context, he goes a crossfit gym. All they do are classes with a coach. It's not a regular gym like Gold's where random people are milling around doing their own workouts. Every Saturday they do partner workouts. My H and this woman were also both part of the competition club. So, they were partnered together on Saturdays most of the time.)
The part about your story that concerns me is that your W defended this other guy and dismissed you. She should always have your back over everyone else no matter what. Also, if she doesn't demand respect from men, she needs to work on that. There is something wrong with her self-esteem and/or character if she allows people to disrespect her. Has she done any IC? IC needs to be done by the WP before MC is even considered.
