A Girl I Liked F*rt*d And I Now I'm Less Attracted to Her

I was at my little cousin's birthday party and my sister brought her friend maxine, who I've had a huge crush on for a while now. well, not anymore I don't. I was talking to her for a little bit when she went over to give one of my cousin's friend's some soda, and when she bent over a little bit I heard a little f*rt noise. I'm positive it was her, because she had that embarrassed look on her face. It's like immediately after that, I just lost all my attraction to her......I can't really explain why, it's just that I would think a girl of maxine's beauty would know better than to do that. And now every time I see her I always think of her f*rt, like I can't really concentrate on talking to her, I just keep thinking about what happened, and I think she's beginning to notice. I know it sounds terrible of me to judge her, but I just lost my attraction to her after she passed gas.
