Was the kiss sound she made a goodbye kiss, go our separate ways?

After hanging out with this girl for the second time after we hugged at the end of the evening as we were letting go of each other she made a kissing sound and since then we haven’t spoken for a week since I last sent her a message and she never responded. Plus I had asked her out again and her response was that her schedule is really busy but thanked me for the invite. So to me it seems she kissed me off, no longer to want to see me.
