Just Confronted - A Litttle Confused

[Quicksilver264]

What about the FIRST guy, the one she works with from time to time?

Should I call him or email him? I don't want his wife to find out, but I want to BURN BRIDGES between him and my wife so she WILL NOT RUN TO HIM as this FB affair collapses.

She may revert back to this first guy now because this guy is married, and my wife knows I know.

Married cheating people often take comfort in each others' deceitful situation, and find excitement in sneaking around together.

They both would have something to lose, so I want to nip her running back to him by confronting.
