We all have those feelings (of revenge, hurt, wanting to get back) when something doesn't work out, but they won't get you anywhere. He'll be left with a feeling that he is better off without you. You'll still feel bad. If you want revenge, you go on to a happy life and forget about him. That's the sweetest revenge, and it's the healthiest one for you. Stop thinking about him and what will happen. He'll get what he deserves, either way.
You know my story. I could have been consumed by self pity. Where would that have gotten me? Instead, I chose to improve myself and my life. I chose to leave the past behind me. I chose happiness over revenge. You can do that, too. Your life will be much happier and more complete if you do.
