Everyone has bad memories - and all you can do is try to put those memories into a rational context. You have to learn to accept that sometimes people aren't nice, and you can't change them, no more than you can change the past. Try to see this person for what he/she really is - a sad human being. Once you are able to do that, the memories won't be nearly so painful. It's all about accepting things you can't change. Unless you accept it, and, in your mind, put it into its proper context, you will allow this person to continue to hurt you. Keep your chin up, be strong within yourself - and good luck. x
