I don’t know what to say. I (M26) persuaded her to go on a date with me, and then on another one. Things went really well between us, but we still agreed that we were just friends. Initially, she was pretty reserved and shy, but I could tell she was falling for me (although I didn’t realize how much). Then, one day, she asked me if I was attracted to her. I told her yes, and then we kissed and had sex. Soon after that, we became very affectionate with each other, which momentarily confused me. I could tell she now had strong feelings for me, so I confessed that I didn’t share them and that I wasn't looking for a serious relationship. I had actually mentioned this from the beginning, but I could see how much it hurt her when I reiterated it. I feel bad for her.

I don’t know what to do. I care for her, but we obviously want different things. I know I made a mistake when I had sex with her, but it's too late to change that now.
