BW 53 WXH 56 & still bewildered
Just wanted you to know that you've been heard.
My situation does not fit your question. But I can say that although he did not leave for the OW I kicked him out because he refused to give her up.
Oddly, we've been divorced over a year and I'm moving on well but OW remains married to her husband and my ex still talks about coming home to me. Some very unhealthy dynamics. There is NEVER a day that I regret taking back my power and moving forward.
Just trust yourself, then you will know how to live.
