<human>: Can you provide a brief rundown of the text in within 3 sentences?

When I started class in early August, I met this wonderful girl. We got along quite well and I felt really good about it. I have never been all too good with girls, but since I am in a class that is predominantly female, I thought I should just get going from the start.

From day 1, I felt like there was some kind of connection. Her looks are quite dashing and I made a mistake all too common: I instantly had a crush on her.
Now, I have had a crush before and it has always just ended with me getting over it and moving on. This time, it was different.

To my delight, I would wind up in a study group with her. This means that I sit at a table with her every day, we make all our group work together and help each other with homework.

Throughout the last couple of months, my crush started developing. It quickly became an obsession, she would be all I could think of. In class, I could not concentrate, I could not sleep at night and all my interests became so very trivial.
After a while, I did decide to do something about it, for the very first time in my life. One night, with the courage of a couple of beers, I decided to ask her out. It was nothing romantic, only a text. She did not respond until the morning after and my nerves were absolutely destroyed.

The response though, would not help. She was flattered, but already had a guy. Cue the heartbreak, the sad music and all. Now, I thought this would at least give me closure, that I would be able to finish it there. But no, it never is that easy!

Everything that I felt for her has started blossoming up again. I can not concentrate, I can not sleep and all I think about is her quirky smile and joyful laugh.

This is my first time dealing with these kinds of things and also my first time posting here, but I thought I would search for help around here. Thank you for your time
<bot>: Fell in love with a girl, asked her out, she has a guy already. Still in love with her, do not know how to deal with it.
