Master Don Juan
Thats really a crazy situation! Gonna do that... If she comes back here I will gonna find something to protect me legally.I've been stalked four times (perhaps more if they were good enough stalkers).
Her next move will be to push your buttons. She wants a reaction (any attention is better than no attention)
Then... after she accepts that you aren't interested, she'll feel the need to regain her pride. Expect further drama and unkind situations (one of these keyed my car) .
If you think it's serious, file a restraining order. It's been years since I've encountered your situation, but with the climate *these days* you need all the evidence and protection on your side.
