WW and I had our first MC session. I was not a fan of the counselor as I felt that she didn't really guide the discussion or offer insight at times. So, first question is that normal?
Next part - I walked away feeling that we had made a small step forward... primarily because WW agreed to cancel a trip where there was the opportunity to see the OM (the trip was scheduled a long time ago and was not originally intended to be related to the affair). She also agreed to one more counseling session, but nothing more.
She left the session and was very angry/upset. She told me later it was because the session reminded her of the reasons she resented me/hated me. She continues to focus on bad parts in the past or on fights we had. She doesn't believe anything will be different going forward.
Is this a normal reaction at this stage?
You simply abandoned your first thread without following through on the advice and without fully answering the questions. If you had stuck with the people who took time to give you advice, when you mentioned the possibility of marriage counselling they would have talked you out of it.
It's good that your wife agreed to cancel the trip, but she should not have left the session feeling angry.
Traditional marriage counselling is a disaster when there is an ongoing affair in a marriage. Most counsellors do exactly what yours did by allowing the couple to fight and lovebust by arguing at the session in front of each other. They don't know how to stop affairs and they don't have a programme to rebuild love in the marriage.
You should stick with your original thread. Go back there now and answer the questions you were asked about exposure. Follow through on the advice.
