How can someone get notifications when I do anything on facebook?

She probably subscribed to your comments, where every time you post something she gets it on her phone. Or maybe she is always looking at your profile. If there isn't any way to delete her or block her from Facebook, try calling, texting, or telling her in person that her constant likes and comments on Facebook are annoying you. Since you already asked her, try telling her again so maybe she'll get the message. If she still doesn't stop, don't reply to her comments on Facebook. Hope I helped.
