<human>: Can you condense the text into three sentences or less?

So I[20m] went on a date with this girl[18F] who i've hung out with before because she was interested in a mate but he didn't reciprocate. We got to know each other and went on a date  which just involved walking around the shops having a fun time and dropping her home 4 hours later. 

The following day we meet up and catch a movie, she comes back to mine and we did some things. Almost a week later, my mate comes back and shows me this text that she had sent. 

She said she was roofied the night we first went out and that she couldn't remember what she did or most of  the day when we went and saw a movie. She said she was acting wierd and wasn't herself, saw the doctor after seeing me and found out she was roofied the night before. 

She didnt tell me any of this and during the date seemed absolutely fine and normal. What does this mean? Am i a bad person for doing things with her?
<bot>: A girl i was seeing was roofied the night before we did things and she didn't tell me but claimed to our friend she didn't know what was going on.
