Oh boy, but you're soooooooooooo.... And can't you talk to her normally? Tell her to give you a break?

Talk, say what's up and cut yourself off.... And for the future avoid some strange love affairs, such always end badly

I tried to talk to her, but she doesn't listen. She thinks it's something important between us, that we are destined for each other. She says she will fight for me until the end.

so disembodiment will be the best, the ritual of disembodiment

You need to set clear boundaries. Tell her firmly that you want nothing to do with her and that if she doesn't stop harassing you, you'll report her where you need to. Don't allow yourself to be terrorized.

You can't let her manipulate you. You have to be strong.

Maybe you should also think about some energy protection? There are various ways to ward off negative energies and energy vampires.

@wiciol That's what I think, too. For example, you can carry black tourmaline or obsidian with you to absorb negative energies. You can also perform a protection ritual with a white candle.

Or perhaps the Tarot distribution would suggest something? Cards can help you understand the situation and find a solution.
