Once a cheater always a cheater
Mindy should never have been surprised about her husband. He had a wife and she had a fiancé when they had their affair. What made her think that he would have changed? It's statistically proven that the odds of a cheater continuing to cheat are quite high. If Mindy actually learned Statistics she would have known this.

So where's Mindy now?

She's divorced, unemployed, bitter and unhappy. She cannot understand why any of this happened to her.

Hmm, I think we can.
