<human>: Can you condense the text into a few key points?

I'll elaborate more on my story.

There was a cute girl in my Spanish class, and I eventually got the balls to talk to her. I got friend-zoned hardcore by her, but I stuck around because she was really fun. Then she met my other best friend, a guy I met in kindergarten, and they dated. That was a very painful time for me, but it eventually ended. I slowly began to come to terms with the fact that I wouldn't date her. I watched her go through relationships, longing quietly. 

One day, I helped her with a breakup, and she said thank you, then kissed me. Everything changed from there. After two years of being friends with her, I was actually in a relationship with her. We never made it official, or went public, but it never bothered me. This is the girl who I've harbored feeling for (that she knew about) for 2 years, and now I have the perfect relationship with her. There is no doubt in my mind that I was wholly in love with her.

However, one day, she points out a guy to me, and says she finds him attractive. Three days later, She's dating him, and my relationship with her is over.
<bot>: I met a girl, Got friend-zoned, suffered watching her with other guys, broke friend zone into possibly the happiest time of my life, then she leaves me.
