Additional details:
1) I am absolutely sure
2) Close enough that we spend evenings with them 1-2 times per week
3) The cheatee has expressed to me multiple times how upset they get when their spouse is checking out people and flirting
Sounds like he\she will find out soon enough on their own.
Consider this: You tell the person being cheated on, they "give you up" as the source... now you're in the middle of it. you don't want that, trust me.
These things tend to work themselves out. If you MUST say something, say it to the cheater....
