You can only forgive when you are ready to. It's really not good to keep stuff in that hurts you either. When you heal from pain you have got to bring it to the surface, and accept it for what it is. I know that feeling so well with revenge. You need to remember that when you act on revenge all it will do in the long run is hurt you. Revenge lets someone else control you, and the energy will feed onto that person. When you forgive someone that doesn't mean that you need to like them. It just means that your letting yourself free from the hurt.
