I’m bemused by your response, I must say.
If you’re a straight women, it’s expected you will partner up with a man. Do you get that? Heterosexual women are expected to partner up with heterosexual men, and vice versa.
I know you - individually - married your Dave or Nigel or whoever because you wanted to. Don’t worry. 
But on a societal, population level (OK?), straight women are expected to partner up with straight men (and vice versa).
And straight men are our greatest threat. Not any of the things that we tend to find frightening. Like, I dunno, snakes or poisonous spiders or sharks or volcanoes or earthquakes.
Men.
Clearly, many of us - myself included - partner up with with nice men who are no threat. But far too many women are not so lucky.
They are assaulted, abused, beaten, raped and even killed by the men they love and choose to live with.
No-one else on the planet - including no other species - CHOOSES to partner up and live with their most real and present predator. Zebras don’t shack up with lions. Mice don’t cohabit with cats.
We do. Ever day. Many of us a lucky. Many of us are not.
Do you get it?
