CM, Sorry you are here. Yes, there is a lot of pain on these boards, but you will get lots of support and friendship. I don't know what I would have done without the board. It becomes like a lifeline to you.
As far as the exposure, there are different outcomes. Some have had success with it and others it really didn't make a difference. In my case it didn't make a difference. H showed very little remorse.
I do suggest that if you expose that you have some hard facts to make yourself credible. Tell your spouse how you know. Don't let your spouse think you are just assuming things. Your spouse will try to deny it, but if you have facts it will be impossible for them to deny.
I wish I could give you more advice, but I haven't been very successful myself.
Hugs, Yoyo
