Well, everyone might not see it as a burden and everyone might not feel bad about not returning your feelings. In fact, some people might be flattered. I've had some people confess having a crush on me. With some guys, I was flattered and with some other guys it made me uncomfortable. But I guess it depends on how aggressive the person may come across. I hope it works out for you. Who knows, maybe she does feel the same way. Good luck!
