So true sometimes people open our eyes allowing us to understand a dysfunctional belief system we have been running within ourselves. We're forced to deal with our false beliefs and come out stronger with a new empowered reality. Without the adversity we wouldn't have this opportunity. When we don’t forgive, we make someone else’s behavior "about us". We carry their dysfunctions and make them our own. Validate yourself, what they did (do) ,what you allowed and move on stronger.
