<human>: I have been talking to this girl for around a month and half. We talked almost every day and I really began to like her.

We hung out a month ago before she went back to college and it went great. She kissed me and told me she had a great night and that she had a crush on me.

I noticed that she often texted other guys but I did not see it as a big deal because she was still single. Yesterday I went and visited her for a day at her college.

Again I thought the day went good overall. Although I was a bit nervous she said she thought it was cute that she made me nervous. The one thing that did upset me was that she was texting another guy next to me throughout the day and knew that I saw her doing it.

At the end of the night we made out and told me what a good day she had with me, and I was very happy about the whole experience.

Today however when I asked her the next time I could see her she told me that she was going on a date Friday with the guy she was texting and changed her mind on how she felt about me, and that she just wanted to be friends. 

Is it stupid to continue to try and talk to her and maybe have her explain why she made this decision?

Can you give me the gist of the text in a nutshell?
<bot>: Girl I had a crush on acted like she really liked me back and then changed her mind about her feelings and destroyed mine in the process.
