<human>: Can you provide a brief overview of the text?

I dated this girl in high school and she was really the first person in my life that believed in me 100%, all the time, no matter what. We were always there for each other and it was an awesome time in my life. I became depressed (just for other reasons) and I became irritable and unable to communicate my emotions to her.

...So she saw her cue and asked me if I wanted to break-up. I was just so anti-social at the time I didn't care--I didn't feel anything even though I loved her and I was letting her go. 

She was absolutely devastated because of this and it really took a toll on her and she became very bitter and introverted. My friends nor I really talked to her (or really saw her) much after our break-up. We talked a couple weeks before college and she still seemed very bitter and defeated.

 It moved me deeply that she was still in this state so I made a point to, every once in a while, message her on facebook asking her to get coffee just so we can hash things out. This turned into her getting a message about once every six months... I never planned it, it just happened to be the best times when we would both be off for break. 

At first she didn't answer my messages but eventually she did. Her message was a clear no and to never ask again. Then she blocked me on facebook so I cannot communicate with her.

Over 3 years have passed since we dated but I still can't get her out of my head. I still see things on the street that I would love to tell her and I dream about her non-stop and I can't get them to go away. 

I just don't know what to do. I can't think of any way to connect with her. The last thing I ever said to her in person was "congrats" at graduation and that's all.
<bot>: I broke up with my high school sweetheart; 3 years later I still can't stop thinking about her and I don't know what to do.
