Suggest they should get a mail order bride then, or stop being such an unlikable cunt by raising their self-respect standards.

In my experience they seem to shut up when you suggest that.

What you said is all true, and there's no excusing that level of rottenness, but I do think there's a deeper component to it that they do not acknowledge.

They want to feel good about themselves, which at the core is not unreasonable, but they've built up this whole misogynistic mythology where they need a conventionally attractive woman - mind, body, and soul, in order to feel safe and happy.

But I'm convinced that even if they somehow stumbled into this unlikely relationship they would still be miserable.
