So basically a male friend has confided in me that they have slept with another (male) colleague. My friend doesn't know that I know our colleague's wife through the gym. We aren't best mates or anything, but I see her a few times a week, occasionally we grab a coffee after the gym if we have time.
My friend says he only realised our colleague was married after it had happened. He said that our colleague confessed his feelings after a few drinks and apparently my friend knew he was gay for ages.
I have worked with our colleague for years and even attended his wedding. I just can't see him being gay let alone cheating.
So either
A) colleague is secretly gay and cheating on his wife
B) friend is lying
My friend loves drama but I have no idea if they would stoop to lying about this. Also have no idea why I have been involved!
WWYD? Do I say anything? Ignore it? Play dumb?
