>write a list of all the small things you resent about your ex and your relationship. Make sure to include every lie he/she ever told and every action he/she ever did that caused you pain. (Plus, everything he/she did not do, that caused you pain).
>Study the list and try and understand what may have motivated the actions. You might come to realize that many of the things he/she did were done not out of malice but out of fear, insensitivity or ignorance.
>Accept that what happened in the past can no longer affect you unless you let it and, if possible, forgive the person for hurting you.
>Finally, burn the list. Let the burning be a symbol of your release-- from any pain and bitterness that the affair may have caused you (also, you don't want to one day be reminded of your grief if you come across this list insome near-forgotten file). As the list burns repeat to yourself that you are FREE.
