That's very noble of you solution_seeker to want to forgive someone who has persecuted you. As Mike has just said, forgiveness in this way can be beneficial to you in order to move on.
I don't know if you've tried meditation, but here's the basic steps to a meditation which is used by the
Friends of the Western Buddhist Order:
1. First of all you aim to create a feeling of love and compassion towards yourself, perhaps repeating the word 'i wish myself well'
2. Then you think of a close friend to spread this too,
3. Next spread this to someone you barely know, who you feel neutral towards,
4. After this to someone you have bad feeling about,
5. And then finally out to everyone and everything.
The important thing to being able to create this feeling is the thought that everyone is a living and breathing being who on some level have similar ambitions in life.
I hope this helps.
