Girls, if you kiss a guy on the cheek as a "good-bye," do you like him?

I had a friend for about 2 and a half months, we were good friends and had a lot of laughs. I suspected that she liked me and think she suspected that I liked her, I admitted it to mutual friends but never to her. We hung out every weekend with a bunch of other people and I usually just waved and said "Hi" before going about group business. But the day I was leaving, as she was walking home, she caught me walking home. I stretched my hand out and said "I'm leaving Sunday, so good-bye," expecting a handshake. But she pulled me in and planted a kiss on my cheek. Does she like me?
