Yes if there is anything that we should have learned is that what others think or say doesn't really affect what is. Besides, I wholeheartedly believe that the truth always comes out eventually. I had a wonderful therapist tell me that people can only pretend that they're something they're not for only so long. If it's not our true self, we fall back into who we really are, if for nothing else then the pretending just wears us down. That's why most of these relationships have a shelf life. They're not based on who these people really are but some fantasy.
You know we can fool anyone and pretend to be anything but in our hearts we know the truth. Bottom line is, if WE like who WE are should be what truly matters!
