So far I only considered the following:
-Getting really stingy, on money, food, heating, cancelling home internet
-No more affection and intimacy
-Refusing to eat food she prepared
I don't quite comprehend the combination of citing that she "just won't leave" and also admitting you're continuing with affection and intimacy, paying for things and eating her cooking.
"Just won't leave" implies that you've told her you don't want to be with her, yet that list implies you either have not or you've effectively nullified that sentiment by continuing to be in the relationship basically to the fullest extent.
It's strange.
