If a guy kissed you on the cheek while you were hugging, what would you think?

OK, I've been friends with this girl for like a year. I have a crush on her and I think she may like me.

We went to the fair last night and both of us had a lot of fun. Went on rides, shared funnel cake, saw a concert, blah blah. Anyway, she drove me home and when we were hugging, like we normally do, I kissed her on the cheek. She looked normally surprised and she was like feeling her cheek but we didn't say anything about it.

We hung out again today (went to see a play and then I went to go help her with her homework at her house) and neither of us brought it up.

We hug like every single time we're done hanging out but this was the first time I kissed.
