I work on forgiving people who have abused me *for myself*, not for them. I forgave my abusive father but never told him and never spoke with him again. It gave me a lot of peace, to forgive him. It's an approach that is advocated in a lot of religious traditions too, probably not without cause but I'm always skeptical of organised religion myself.

Admittedly, it has been harder for me to forgive other people who have abused me.
