@ethm777 I just had a therapy today and I took the opportunity of it to ask about telling one of my friend. She said that it would relieve me for sure, and that I need to talk about this so I can find a way through. I had a conversation with my wife tonight, and she said that she would think about this and I think that she will tell me that if it help me, I can talk about this. I told her that it was pretty hard for me, as I did nothing, but I have to live with this secret.
One thing I find really hard is when we are together with other friends or family. When it happens, it is draining all my energy. Last saturday, we hade over 20 friends at our house, and when the last one left, I just felt on the floor. I find it hard to look happy when it's not the case, and I find it hard that I know the truth and everyone find her so nice... When I think that Christmas is coming, I fear that I will have a hard time. My therapist said that maybe I should consider that we won't go anywhere together to make sure I can go through that.
I asked my wife to look for a new job, which she's doing. She's not working with the OP anymore, they're not even in the same building, but I need her to be away from him. However, she's going through a hard time on therapy, and the therapist said that she had to understand why she did that in order to rebuild herself. Right now, it appears that she did that because of a real lack of self esteem which is going back from her childhood, and kept secret all those years. She's trying really hard to rebuild our relationship, herself and she feels deeply sorry. The therapist said that if she get a new job right now, she may lose everything because it is the last thing where she has a little esteem from people (She has none from me right now, and our kids don't know what she did, but they know she made me terribly sad).
My wife also made a timeline. It was hard at first, but it is helping me understand what happened. It is turning out there was no love in this, and it was purely mechanical. They was no passion as they were also talking about their job before and after they did it.
Every time they did it, she had no intention of doing it, but couldn't say no. The last time they did it is the saddest of them for me. She said "yes" to him only because she didn't want him to be sad. I told her this was sick, it was her coworker, she didn't want him sad, but didn't care about her husband and kids? That's totally messed up for me!
I also had constant anxiety, especially on Monday. As they did this lunch time, at his place, I was totally freaking out around noon. As time is going over, I feel less and less anxious. She is sending me emails 2 -3 times per day, and always calling me around noon and 13h00 so I can know she's not away from work.
It is really helping me writing this stuff, I'm glad I found this place!
