Just went through your thread and yes there are some similarities.
Although in my sitch there was never any A. I think that mentally there kinda was. She was not even contacting him, it was just kinda in her own mind. She saw an old flame at a funeral and convinced herself that she had always been in love with him.
The night after she saw him she came home and made passionate love to me. But that was one of the last times. We had sex a couple of times after that but then she told me ILYBINILWY
In T she told me that she had always been in love with OM and should have never married me. Said she married me for all the wrong reasons.
Many months later she told me she had been wrong about being in love with OM. It was left at that. As far as I know she has never contacted him at all. It was all in her head. We had gone through hell and life was pretty hard. And I just wasn't any good at R's.
So I guess it's kinda strange but it does sound similiar.
I hope the best for you and will continue to check in.
