I ignore her and she tries harder?

For 2 weeks I've been trying to distance myself from this girl I go to school with like replying slow to her texts, not saying hello or goodbye, talking to her less, avoiding her, etc and in response she's been more persistent and initiative such as video calling me, invading my personal space (like really close, sometimes I have to push her away), touching me, unwarranted hugs, she'll even pull and drag me if I try to leave or if she sees me in the halls.

And it would seem that she likes me and I'm just being an idiot, but the thing is I confessed to her a month ago and she rejected me (even though she gave hints and signs she liked me back). So I'm really confused.
I ignore her and she tries harder?
