I feel like guys lose when they pull this kinda stuff.
Setting up some big "reveal", trying to make a big deal out of it...that's feminine. Leave the "call-outs" to women.
Men are supposed to put on a brave face, remain calm, and end the relationship in a clear manner.
All he's done is shown how much he really cared...and guys should be above that.
What's next? Are guys about to start barging into their partners place of work, children in hand, talking about "how could you"?
I've no defense of a cheating whore. That bytch can rot. But the guy doesn't look "cool" here...he looks like an emasculated dork.
