I developed feelings for a shy, sweet introvert girl who was flirting with me a lot (actual flirting and seduction, not just being nice). Turns out that she's extremely sexually promiscuous and has been for years and that she does the seductive flirtationship thing with many guys. There's only one or two guys she has any serious feelings for and I'm not one of them. I feel broken. I just want to lie in bed all day.
