If a girl knows I like here and she is avoiding me what does that mean? dose she like me or not?

I see what you meen,Happens to everyone(more or less)but it is how she acts when she avoids you.Does she glare at you when she walks by or does she have a relaxed face.or does she completely ignore you.Try what im talking about and see what happens.and dont get your hopes down if she glares or ignores you i could be mistaking all girls are diffrent just pay close attention.
