Is this girl digging me. why would she reject my kiss?

She broke up with her boyfriend 2 weeks ago. We been texting back and forth for 3 weeks now, and last night we had our first date. We met at the movie theatre. I told her i loved her. she didn't say she loved me back, but she said "aw thats cute". That was first date i had ever been on because i had never dated a girl before or had a gf. I bought her nachos, candy, and a slushie from the movie. and paid for both our tickets. at the end of the night when i leaned in to give her a kiss She put her hand over my mouth and said " im not a kissing type of person. i don't kiss people. it has nothing to do with you i just don't like kissing people. it has to do with sanitation"
