Fuzzy, I was once told by a minister that you can forgive but it's wise to not forget so that you can keep yourself out of harms way when you know the behavior will be repeated.
Some people don't understand why something can hurt you. You can tell them the reason, but they don't have to accept it or understand it. In that case, you need to protect yourself from their behavior. However, if you don't forgive them, it will fester inside you like an infected, pusy wound and it can reach the point of controlling all your feelings and your entire life until you don't trust anyone. It can also lead you to keep looking for similar relationships of all kinds because it's human nature to look for what's familiar to us. Most often, we're not even aware of what we're doing.
Please take care of YOU. Do what YOU need to do to keep yourself safe.
{{{{{{{{{{{{{{{{{{{Fuzzwad}}}}}}}}}}}}}}}}}}} I love your gentleness of spirit, Dear One.
