I dont have any advise for you except i would not be able to not confront my W if i had proof (i.e it wasnt all in my head). I am incapable of letting that slide, similar to Sandhi's story i would tell her to make a choice Stay and work on the M or GTFO, away from me, away from our house and away from our children. She may choose to go in which case do you really want to save the M with such a selfish person, or she may choose to stay but that doesnt mean you go back to being a loving husband, there is still plenty of work to be done.But thats just me.
Read it over and over again. Remember whatever she tells you it mostly be lies. Trust nothing what she says and 50% of what she does.
