A male friend, who I once had a thing for, which fizzled out very quickly. We're not now especially close, but see each other fairly regularly in a group and he's one of those friends I could call in an emergency and know he'd do what he can to help, without hesitation. He's considered a bit of a ladies man, but I've long suspected he might be gay and the women are all a cover. There are a lot of women in his life, but none of them go anywhere. I wouldn't say he treats them badly, most remain friends (like me), but he takes relationships so far, then backs off rapidly as soon as the women are starting to believe.
Anyway a while ago he confided in me that he'd slept with his best friend's wife, before they were married and while they'd split after a row - a short lived split as it turned out. Not a great situation, but they were both single at the time, life's not black and white etc.
Now, he's told me he's also slept with the husband (while they were together). He hasn't said he's gay or bi, but that it was a drunken "experiment".
I'm quite good friends with the wife.
So I have two issues. If he is using all these women, I don't like that, and I have a friend who's husband has cheated in a devastating way.
But it's none of my business....?
