<human>: Can you give me a shortened version of the text?

I went out for drinks on Friday with someone that I work with. She is 28/F. We went back to my place afterward. I was very clear before we had sex that I was not interested in a relationship. We did anyway. 

Last night, she came over to watch some NetFlix and we cuddled a bit, but nothing serious. I wasn't really looking too far into it. 

That is when things went wrong. I made the unfortunate decision of making a joke about one of the other girls at the office being jealous. She got really hurt and talked about how she is always the second choice. How I just confirmed what she had thought since Saturday. How every guy she has been with has "used" her.

I feel horrible. I don't consider myself to be a bad person. I apologized several times and gave her a lift home. I don't really know what else to say or do?
<bot>: I hooked up with someone from the office and now her feelings are hurt. I feel horrible, and am not sure what, if anything, to do.
