<human>: I had sex with someone I met only twice and now I feel so much guilt and shame. I didn't even get dinner. 
I feel cheap and like I ruined an opportunity for a relationship with a guy. He was very intelligent, funny, and he listened to what I had to say... We didn't do anything the first night and he respected that... I thought that he was a decent guy but he mentioned he just got out of a relationship at the beginning of January and wanted to keep his options opened. He said we won't do anything I didn't want to do and I knew he would have waited..
We met up again two days later and had sex.... I don't know why I went with it because now I feel like what I actually wanted was a relationship and jumped to conclusions that he wouldn't want one with me. So now I have this horrible feeling that I made a bad decision and I feel sad, lonely, guilty, and shameful. It's obvious through texts that he is no longer interested. 
So please help me and talk some sense into me because I know that I deserve better but I just need some support. I haven't been able to focus on school and have been missing work so what happened has become an issue for me... Thanks ahead of time.. I appreciate it.

Can you condense the text into a few key points?
