How do I get over the resentment I feel caused by the cheating ?

Asked by Amazebyu (488) August 31st, 2010 from iPhone

I want to be able to move on and as I heard I would only be able to do this after I forgive my ex and leave all resenents behind. He has a sexual addiction, which he confesed not until he got cough sleeping with a prostitute. Broke up and haven’t seen him or talk to him since then. I’m not even contemplating the idea of getting back together but I do want to move on without negative feelings. Please any advise would help. Thanks.
