If you can't bring yourself to forgive, you'll end up feeling frustrated, guilty, ashamed and a lot of other things. You can't forgive until you process all of your hurts. You won't even need to forgive I think, because you'll be at a place of peace within yourself and you'll come to an acceptance of what happened or what is happening. That doesn't mean you like what happened or think that it is ok, and you have every right to feel that way, but it won't bother you any more when you have dissolved all the emotional charges. See EFT short cut here.
You couldn't relive your life, skipping the awful parts, without losing what made it worthwhile. You had to accept it as a whole--like the world, or the person you loved ~ Stuart O'Nan
