Do not fool yourself into thinking that you are some how to blame for someone’s unfaithfulness.
Do not compare yourself; Do not cross-examine yourself; Do not sit and wonder in what ways you weren’t pretty enough, or good enough. Or what it was you could have done differently.
People cheat not because they are lacking something in their relationship, but because they are lacking something in themselves.
It is not your fault that castles cannot be built on eroded foundations.
