No, we're not talking about cheating in school. We're talking about those sad moments when you find out your partner cheated on you.

As the saying goes, "caught cheating once, shame on them... caught cheating twice, shame on you." In other words, it's okay to work through infidelity once in your relationship, but if your partner does it again, take a hint.

Nobody deserves that much pain in a relationship. So walk out after incident #2 and move on to someone who can be happy with just you.
