What to do?

Consider her nothing more than a future mate.
Not a lover or girlfriend. Remove that from your thoughts for now. Just try make friends with her.

That is some really good advice, it should help me be able to talk normally to her if I just consider her as a friend.

Since I already 'tried' to start an interaction on facebook, very simply lol. And my comment ended up getting deleted. I would like to know why she does that or what that meant? That kind of raised a lot of questions in my head that I can't figure out and it's not helping very much

But I don't want to seem like a stalker, so i'm not going to try and run to her to say hi, i'll just say it casually the next time I see her around doing my daily things.
