I don't think she hates skating, but I think she's not too crazy about the media attention. In one interview, she said she wouldn't have her child to figure skating. She said having a normal life as an ordinary citizen was probably the best, which to me seems to indicate that she's tired of the media. She never started figure skating to become a super star.
That's just too bad, because even if she retires she's never gonna have that "ordinary life" in Korea....
