I have heard about the predators/victims/saviors triangle in man/women (or man/man) relationshios.

I'm not sure what to think of it. It sounds scary to be stigmatized as such.

Have you heard of it? What does actually the notion of predator mean?

Is a seducer or player considered a "predator"? because he supposedly doesn't really care about the girl but just wants to seduce her to get laid? Why is that a bad thing that a girl needs to be saved from if no false promises has been made?
