It's quite difficult to give you an advice . . . The best thing to do is to see if that person shares the same feelings for you.If not it's little you can do.Anyway , I think you should ask yourself how much do you really like him.Maybe it was just a short attraction and it'll pass with time.I don't know what to tell you more . . . What are you going to do ? Maybe I can tell you if it's the right thing or not . . .

Why did you think you hated the person? That should be explored. Was it because you subconsciously had feelings for the person and you didn't know how they felt so you began hating them? Did they do something wrong to you? If they didn't do anything wrong and the reason for why you began hating (although "hate" is a strong word) them is frivolous then I don't think there would be anything wrong with you sharing your feelings. Oh, unless he is involved with someone then I would hold off on expressing your feelings. best of luck!
