I may have to do that, even at the cost of them wondering why in the world I'm cutting contact with them.

She says nostalgic things (I mean why out of the blue mention memories from years ago) and then make suggestions that I am the cold one giving her a silent treatment. It is an insincere move to make me look like the bad guy.
