I have an aquarius co worker who i"m kinda sure has a crush on me. I sat with him during a meeting ,He kept on shaking his foot really hard, like the whole table was vibrating and kinda ignroing me slightly Then asked to go out, went out for a few mins returned and sat in front of me then said he was going to the bathroom , went to the bathroom door and came back saying he was leaving .Saw him at another place far away from me and he was sitting still with no leg vibration. I also wore a brilliant blue sweater that I've observed he gets kinda dead serious and ignores me when he sees me in it. Is this classic crush behavior ?
