Confront and Heal yourself before you try to confront/forgive your abuser:

Forgive yourself for holding onto this hurt. For it has disallowed you to move freely forward. Look back and remember your self as a child sitting in the sunshine and pick her/him up in your loving protective embrace. And walk away with this innocence and tell them that they are safe now and noone will ever hurt them again. Hold this child in your loving heart. Allow them to stay for as long as they like. Knowing they are safe now to play and grow to feel what love is. And allow yourself to feel this too. Now you may keep them in your heart forever or move on when they and you have healed.
So when those ugly memories come and say rember me say with compassion "no", they nolonger reside here and let those emotions go. This is a process and will take time. Alot of time and patience,so be gentle and kind to yourself and inner child.
This has been my personal experience it has helped me. I hope it helps you, let me know.
