Aw, but this was looking like so damn much fun.
First: The self congratulatory tone, editing and editorializing of the narrative are a pretty clear tip-off that things didn't happen as presented, if they ever happened at all. However, it's great fun to scream at each other over this hypothetical situation. Which is pretty much all we can ever do in this crazy, mixed up world. And other such maudlin shit.
This person is lying to me, to my face, getting indignant when I question their lie, all to try to force me to shoulder a lifetime financial burden I do not want and did not consent to even implicitly? I have absolutely no interest in being kind or nice to her at this point, and an active incentive to put as much salt in the wound as possible.
The "they are clearly both irredeemable motherfuckers" consensus has already been reached. But a point was missed. Yes, entrapping a man through the creation of life is a hideous crime unique to femininity*, in the same way that rape through physical force is (generally) unique to men. Any reprisal invites applause, in the same way that a rapist receiving an automated lopitoffame from a nightmarish vaginal device seems entirely awesome, though it's impractical and cringe inducing for dick-havers.
Except it doesn't excuse any of the male character's subsequent actions. It seems like it does, except for the very nature of the violation. Which is what makes both crimes so mindfuckingly wrong.
In his delaying of revelation, he narrowed the window within which it would be convenient and possibly legal for her to obtain an abortion. They're both rat fucked sons of bitches. It's likely that her kid probably will be, too, but that's maybe an unfair presupposition. Certainly not one that would justify an (early, possibly short) lifetime of suffering at the hands of a manipulative harpy.
At least, not as the price of a joke. And bear in mind that I hold those in high value.
*It's one that I'm probably guilty of being excessively wary of, having once witnessed a close relative attempt such an evil manipulation upon a childhood friend. There are, in fact, few things I am actually terrified by, and this one pretty much tops the list. Though it comes in just below my fear of strangers putting a knife inside my scrotum when I take the time to think about it. The scales just might have been tipped.
