Forgiveness and talking about the past?

I think I understand what you're saying/asking. Usually, we know when we're talking to a friend or advisor for "theutic" reasons as opposed to when we're gossiping and speaking spitefully about someone. If you feel like you've taken steps to forgive but still feel like you need to process what has happened to you, it might be helpful to speak with someone who is/was not involved in the situation, someone who is a good listener and who has proven to you they have a level head and won't just tell you what you want to hear. Talking directly to the person who offended or hurt you may not be the wisest route. They (should) know they hurt you because you forgave them. You wouldn't have done that if they didn't do anything.
