I wish, in this answer, that she’d given some space to the possibilities of a childfree life:
Oh, the dream. The god damned man + baby dream. Written by the High Commission on Heterosexual Love and Sexual Reproduction and practiced by couples across the land, the dream’s a bitch if you’re a maternally-inclined straight female and not living it by the age of 37.1; a situation of a spermicidally toxic flavor. Of course you want to bring out your six-shooter every time you see another bloated mom hoisting up another squinty-eyed spawn on Facebook. You want the dream too! The man. The baby. The whole god-damned shebang.
But, M, you didn’t get it. Not yet. Not quite ever, perhaps. That doesn’t mean all is lost. This is not “how your story ends.” It’s simply where it takes a turn you didn’t expect.
