Most Helpful Girl
Has this person apologised or asked for your forgivness? If you are not ready to forgive him or her then you simply can't. You're asking us HOW and the answer is that it's all up to you, usually this takes time to heal from. Everyone is different, me personally find it difficult to forgive anyone whose hurt my feelings so when one of my ex boyfriends asked for my forgivness I could not forgive him and I still can't. Healing takes time and you will be able to forgive when you feel ready, when you have accepted what happened.
