I'm supposed to have a plate over one night this week, however her replies and response have dropped enormously from when I first met her.

She is also convinced I don't see other girls and that "I wont leave her" after 2 months of seeing her.

I am planning to cancel on her few hours before I see her, and drop all communications with her by 90%, and bring another plate over. I will say "Sorry girl, something came up Ill let you know another time to meet up" I am not very interested as I used to be.

Happy to cut her off for good, how do I go about it? Keep cancelling on her, or speak to her and let her know that I'm not interested anymore.
