Most of the time I believe the polytards are just excruciatingly stupid whores who can't keep it in their pants, but mommy said to never lie, so they're upfront about how much they fuck around.
With cases like this last one I legit wonder if there's a sadistic angle to this hippie commune horseshit. Woman just went through pregnancy and childbirth: No way she wouldn't be better off just not fucking knowing about the stupid, disloyal, sleazy husband's bang buddy. Dude's being as destructive and harmful as he possibly can.
He's already a piece of shit to even cheat on a pregnant woman in the first place but parading the other bitch in her face and moving her in feels like a god damn victory lap. This woman should sue him for every cent he's worth.
No doubt in my mind this motherfucker would try to bang his teenage son's first girlfriend too. Just to make a point. If your partner is a disloyal pussyhound he's absolutely NOT parent material and you're not just better off without him: You pretty much owe it to your kid, if you want them to have any sort of shot at a stable, normal, good life, to take out the trash.
And what's the sidebitch's role in this? You just tell the kid she's an aunt of sorts until they're old enough to understand? How fucked in the head are these people to agree to this sort of arrangement?
Even a single mom and her new squeeze is awkward as fuck for the guy and the kids, and that's assuming everyone involved is reasonably sane and well adjusted. Being the type of downbad dude or dudette who signs up for poly in the first place carries some really sketchy implications where kids are involved, as I'm sure has been said in the thread many times over.
