When your wife finds out you talked to her boyfriend (and -- if she does -- then I would say you have every right to suspect that OM is not being frank with you), she will try to grill you for what he told you. She will DEMAND that you tell her.
Don't take the bait. There is much strength in being in the position of your wife not knowing what you know; and what you DON'T know. Her default position will then have to be that you know everything (and it's OK to use that term with her -- "He told me everything." Just no details).
