<human>: About 6 months ago I met this kind of perfect girl, she was cute, sweet  and for some reason she fell head over heels for me. It seems like she fell pretty hard pretty fast, I on the other hand didn't feel that instant connection. There was obviously something there, but it took me some time to really fall for this girl. 

In hindsight.. I guess I was kind of a jerk. She literally did everything to try to make it work. I was kind of whatever about the whole thing, I liked her.. I thought she was cute but that was about it. 

After a couple of months things changed.. I started falling for her pretty hard. I always knew there was something there, it just took me a little time to feel what she felt the whole time. I honestly didn't give her my everything in the beginning. I didn't always call when I said I would and I didn't always know what to say to her when we had little arguments so I just shut down. I regret my behavior cause she obviously didn't deserve any of that.

I tried really hard to do better though; and I did. My feelings for her grew pretty damn strong and things were actually pretty great for a while. But then of course.. I had one of those moments where I just shut down. She freaked out and told me she was done.

So, now I can't stop thinking about her. I guess I wish for her to be happy, but I don't know.. I fell in love with her. I don't even know what I'm asking here, I think I just needed to vent.

Can you give me the gist of the text in a nutshell?
