<human>: Can you summarize the given text in a few sentences?

I met my ex-girlfriend back in Istanbul, Turkey, where we're from. We were going so good that we moved to UK together and are currently in the same university.

Exactly a year ago.. There was a rock band contest where I sang, and played guitar with my band. There I was, singing, 'Nice Dream' by Radiohead. I saw her in the middle of the crowd, I literally couldn't breathe. I screwed up a little bit of the song.

After the song, I went there to see her. I got her number, we started dating a day later. I became a romantic, and I couldn't have been happier..  Our interests are exactly the same, I can't count a thing that I like, and she doesn't. There we we're, 5 weeks ago, I was pretty sure that I was going to spend my entire life with that girl. I was taking her out for a romantic dinner, after leaving the restaurant, two guys came and started harassing her, I told them to stop but they didn't. One of them punched me to the ground, I got up and beat them up. She said that I overreacted and that I have anger issues and that I need help. I denied and thought she was kidding for a second, but she was dead serious and told me that if I don't go and get help, she'd leave me. I didn't and she left me, she moved out from our college accommodation. I tried to get her back and she refused me several times alredy even though I did nothing wrong. For 5 weeks I can't eat, sleep. I even failed at most of my classes. Nothing I tried or my friends made for me felt better. She seems sad too but not as sad as me.

That's my story.. My question is, what is the cure for a broken heart?
<bot>: The love of my life left me for a stupid reason, nothing I have done made me feel better. What is the cure for a broken heart?
