I Believe Once A Cheater Always A Cheater

Never Met A Cheater That Has Only Cheated Once

Rare must be the cheater who only cheated on somebody once and learned their lesson the first time. It seems people are more likely to cheat on a partner if they've already cheated once before, whether it be on that same partner or a different one in the past as opposed to a person who has never cheated on somebody once in their life.
