How about this . . . forget about forgiveness. Let's talk about acceptance. You accept that he is who he is and that there is nothing you can do about it.You accept that what happened happened. For me, forgiveness means to let go of my own negative emotions. I will not revenge, I will not hope that he gets hit by a train. It does not mean I am going to forget. I've learned a bitter lesson, but there is no need to let the thoughts of him poison my life any longer.
