IS THIS COOL TO DO?

[Midwest Spy]

I told my wife that I suspected her sister of banging another guy (she's married). My wife said no way, and I said I was pretty sure.

About 4 months later the guys wife came to SIL's house in the middle of the day and confronted her.

My SIL of course denied it all the way, but there's no doubt in my mind it was going on.

I think I'd want to know if my spouse was cheating.
