<human>: Can you give me a shortened version of the text?

I had my first boyfriend at 21. At the time, I was just a college drop out and a manager at a popular retail store. Luke was a handsome and successful accountant. He dumped me after a year by email basically saying I was dragging him down because I didn't have enough ambition and didn't see me making something out of my life. This devastated me mostly because it was my first relationship and I was embarrassed that he saw me that way.  

The week after getting dumped, I decided to completely overhaul my life and make the most of every day. Four years later, I got a $50k entry level position in December and two months ago, I signed my first lease for a one bedroom apartment. Even though I hate his guts, I have him to thank for my professional success because whenever I didn't want to study anther hour, didn't want to send out another cover letter or didn't want to work out, I thought of his smug face and harsh email and it motivated me to work hard. 

Everything is going well in my life now so I want to email Luke and tell him he was wrong about me. Not because I want to get back together with him, but because I want him to know I followed through on all my plans and that he underestimated me. I know most of you will say to move on already and that it'll only make him feel good knowing he had such a powerful effect on me. I know that's the right advice to follow, but even after all these years, it still hurts. I was thinking maybe sending him an email would finally give me peace of mind?
<bot>: Ex dumped me for being an unambitious loser. His harsh words motivated me to become a professional success four years later. I want to send him an email telling him he was wrong about me.
