My first wife cheated on me with a friend. I went to the friend's wife and staged it so first her husband and then my wife would walk in catching us fucking.
If I'm this open sexually and someone still goes behind my back, they're immediately my past.
I've only ever had one bf and he didn't cheat on me.
I forgave her. Things ended a little while later. Messed up relationship in a lot of ways.
Guess why I'm divorced....
I suffered other indignities from #2, the shit, but I don't think I've ever been cheated on.
