Play the game, dont tell her you love her at all - thats suicide.
she hasn't feeling for no one, she's... Strange :D
not strange at all
If she wants you, she will come to you. If she doesn't, don't try to make her, because if you do, any attempt of you getting her to like you will only result in the opposite of what you want.
it's called stalking and you really shouldn't do it as penalties for that kind of behaviour are rather stiff.
