<human>: One of the more well-liked girls (she's the girl next door type who is also very nerdy and quirky) in my college club asked me out. I turned her down. Turns out that a good number of her friends were hiding around the corner to give her moral support. Word spread fast to the rest of the club.

I now realize that I may have been leading her on. I was always nice and friendly to her. I would walk her home and give her my jacket (as I do with my other friends). I asked her about her day whenever I saw her and refer back to things she said earlier. I accepted a homemade birthday present from her in front of everyone. I let her sleep on my shoulder once. During club recruitment week, I was the one that convinced her to join because I thought she was kind of cute. A friend later told me that everyone thought we were a couple waiting to happen. 

I was too naive to see what I was doing to this poor girl. I really want to tell her how sorry I am but I think I've caused her enough pain and embarrassment and I probably should leave her alone.

Most people in the club have sided with her. They see me as the jerk that led her on for months and rejected her when she had to courage to ask me out. And boy, do I feel like one.

<bot>: I turned down a well-liked girl after inadvertently leading her on for months. Everyone in our college club heard and now think of me as a jerk for toying with her.
