Name calling and break up threats/actions... sounds familiar. I'm pretty sure someone I was engaged to was a Narcissist. He called me all sorts of mean names but said he loved me and often threatened to leave, walking out of the door and saying ''it's too late'' ... this happened several times. I didn't know about the issue of object constancy in relation to Narcissists I don't think, interesting. Could someone describe the phenomenon of ''splitting'' a bit more?
