If this person you still love - then I would recommend forgiveness for healing - you can use tapes or read books or online articles on forgiveness.
If this person you LOVED then of course forgiveness will work here as well but in addition to that set some goals to move on. It's time we start realizing that no person is perfect and people will always disappoint us. It is up to us to react appropriately.
Ask yourself one question. This person has already hurt you - are you going to ALLOW him/her to continue hurting you? It's a no brainer.
