All of the straight to the point advice is appreciated, and I am digesting it.
To be clear about some facts pertaining to my particular situation:
the PA that she had via phone sex 6 wks ago was with an out of state friend of 20+ years. He is married, and has one child. I have not made any contact with him or his wife.
The EA is with a divorced man who has been a family acquaintance for about 4 years through our children’s school. Our contact with him has increased gradually over time as our children have grown to be closer friends. My examination of phone records shows an increase in messaging between them over the last 3-5 months. I don’t have any concrete proof that their communication is flirtatious or sexual, and of course that has been denied by my WW. I agree that regardless of the content, a line has been crossed. My wife and I have discussed the issue twice in the last two weeks. I have not confronted the OP.
I have intermittently been on meds in the past for depression, and wanted to see my old psychiatrist, but alas he is retired, so I selected someone from his practice. I did not include that information in my original post, and I see that it reads like depression and anxiety are new to me. I have my first (ever) IC appointment 4 days from now.
I am reading NOT "Just Friends." Thanks to the many who have suggested it.
At the moment I feel better about me, having spoken out loud with my psychiatrist about my situation, and having written about it. There’s a beneficial effect from the exercises of speaking and listening and writing that helps to process it all. Thanks again for the feedback.
