Don't tell me you're actually too stupid to realize she likes you? Just fucking talk to her in person. Catch her to explain things, because you feel that, what people think about you is wrong and it sucks. And you could add; I like you so I don't want you to think of me that way.
Be honest with her, and act honestly for yourself. And stop giving so much of a shit about what flies and what doesn't. Ofcourse people will feel this way about you because even if it's not your intent you would come off as uptight.
