Hate is related to love... if you want revenge it is because some part of you still loves him.
The opposite of love is indifference --- not caring.
Revenge is based on emotions which are ever changing... which means you will never be able to do enough to equal the emotional damage you feel he has put you through... because as time goes by it will feel like he has hurt you much worse.
Throw in the towel... you're finished with him... count your blessings that the relationship didn't drag on longer than it had... and that you have learned your lesson.
Karma is a bitch and sooner or later he will come across someone crazy enough to actually sacrifice their own happiness in order to deprive him of his --- but that person shouldn't be you.
Be indifferent and move on with your life. The greatest thing you can do is do better than him...
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
- James Allen
