This thread has been amazing to me. Sarah, thanks for the starter.
So I also just recently found this site, and until today was just a reader. I've kept myself so isolated for a long time, and finally am ready to participate and share.
After 20 years, we are divorcing. The EA (and later PA) happened a few years ago, with me confronting WW multiple times but getting gas lighted and lied to for an entire year. Went to MC, and found out later there was a lot of lying in sessions. We have tried to R, but I was ultimately never able to trust her again. We went on this way in a shallow and "convenient marriage" for a long time. The proverbial straw was a "white lie", not anything to do with any A. On our 20th anniversary this year, she got home late before we went out for a nice dinner. She was in such a rush she left my card and present at work. Next day, I get the card and gift. Two days later, in our stack of credit card receipts, I find the card and gift receipt dated the day AFTER our anniversary, during lunchtime. Man, after all the MC and during our entire R, the rule was, and is, no lies. None. Any size. It was so small, but so large. It was the end.
So, here I am. The other comments here about feelings of humiliation, reasons to share, reasons not to share, are all so valuable. I just want to thank everyone here for being so generous in words, advice, spirit and support.
