Is flinching/twitching bad sign showing that my crush does NOT like me?

When we were sitting next to each other at a cafe, my leg/knee touched his leg/knee. Then he flinched or twitched immediately. After that sometimes our legs/knees touched each other for a while...( I mean we didn't sit whole night while touching our legs) Later, I realized that he put his leg under my foot. Then I went to toilet. And when I came back, he CHANGED our places and he said that he wanted to look at birthday picture of our other friend. (he was sitting my left rather than right. After that we didn't touch each other)
(Note: I also flinched when his leg touched mine)
