Mum was better at it, for a given definition of 'better'. But I don't know, and I've told him that much, that if he wants me all to himself, he's got to figure out how to keep me.
And it still sounds wrong, it's not as bitchy a demand as it looks, it's just... hell, I don't even know, like you said, not really prone to monogamy, don't really know how it works, so it's up to him to show me.
