Is it okay to feel anger or resentment at this point?

Thanks for reading.

I currently work in college admissions, a job that I love and that I do well. I'm living a comfortable life that I never thought I'd have just a few years ago. As a result, I sometimes think of my successes and struggles.

I think about how just a few years ago, the girl that I wanted to marry broke my heart. And despite being together for nearly two years and many conversations on one day marrying and starting a family, she didn't try to soften the blow and shut me out. She even went so far as to forward private e-mails to a friend of hers and the two of them made fun of me and my ex even called me a failure.

Now that I have gained success, and am living such an accomplished life, is it right for me to feel anger or resentment at my ex even though it has been a few years. Her making fun of me and trashing me was a big reason why I strove to do better but is it right to be angry now? A big part of me wishes I could show her what I've become and show her that she was wrong.
