<human>: So last week I met a guy through mutual friends and we all went got together. We really hit it off, talked all night to each other, he ended up kissing me and getting my number.

The next day, I ran into him and told me to text him later with any plans going on that night. I ended up just going over his house, again, really hit it off. I did not sleep with him nor did he try to make any intentions to do so. When I left he kissed me goodbye and said we should hangout again soon.

I saw him in class a few days later and chatted after for a few minutes. 

Now, I never hear from him. He never texts me. Ignores me in class and won't even say hi. I can't think of anything I did or said that would have possibly drove him away. What could have happened?

Give me the gist of the text in a nutshell
<bot>: Me and this guy totally hit it off, totally out of the blue stopped talking to me and now ignores me for no reason
