First post, not sure if done correctly.

Last night I went to Junior prom with a girl I've known for about a year, and have liked for a few months, and it was an excellent time. All through the prom we're dancing and stuff, and theres a couple of slow dances which we participate in, and a couple of times she looks at me like she wants to kiss me, during the dance she doesn't but she leans on my shoulder which makes me think she's into me. Nothing much happens after that, and the dance is over. So it's like 11:30 pm and raining and I'm dropping her off at her house just like a good date should. Before she goes in she turns to me and kisses me, and at this point I'm thinking a couple of things, 1. I just had my first kiss, awesome, and 2. Yea she's def my gf now. So I go home all exited and stuff then at 11:50 she texts me: 
Her: Sorry, I shouldn't have kissed you... I'm impulsive. 
Me: What do you mean, it was fine. 
Her: idk
Me: I'm fine if you're impulsive, I'm a bit shy and it's hard for me to do things like that, it was excellent
Her: I just don't want you to think it means anything
Me:(at a loss for words, confused and feeling hurt) Oh, k

So since that happened I've been wondering if she meant she doesn't want a relationship w/ me and kissing me was an accident, or if she has feelings for me even somewhat and doesn't want to say it or what. It would be nice to get some help/ advice from people that have been in similar situations because right now I don't know what to think. I still really like her but I'm not sure if it's a lost cause or not.
<bot>: Went to prom with someone I like but am not dating, she kissed me after and then said I shouldn't think it meant something. Confused on what to do now.
