<human>: Could you distill the essence of the text into 1-3 sentences?

Ok, so I asked this girl I've liked for a while to be my valentine, she says yes, and everything is fine and dandy, so we start talking (keep in mind we've known eachother for a while and she had a thing for me back in august) and she asks me to help get this book from this one room, so I agree, I help her, she gets it, and she starts coming back, so I come under the door (it's like a book garage) and I kiss her, it was a short kiss but yeah, and she says woah, thank you for the suprise, and we walk back, going to our seperate classes.

he tells me to message her on facebook, and I do, she never replies, and next period, she had already told her friend, and I guess her friend told her that I did that to her in middle school? But I never had an interest with her, ever, so I was pretty confused by that. over the course of the day I found out that she had told people that I was ruining her life, (WTF?) and she proceeded to talk shit to me and say I'm a dick and that she only views me as a friend and shit and that she doesn't want to be my valentine anymore, so I'm like whatever, wasn't really a big deal, and I guess I made it a big deal by telling a good friend of mine that doesn't really talk? So pretty much my day was really irritating and confusing.

(I copy pasta'd this from a facebook chat, so I didn't proof read it that much, sorry)
<bot>: Suprised a girl I liked for a while with a kiss, backfired on me because of her friend, what should I do?
