I'm going to disagree.
As it's been pointed out before. If Kyan were a stay at home mom, no one would think twice about 'her' staying home with the kids. Even with the support of Perry and his in-laws, parenting 4 young kids is a full-time job. He has branched out and has his coffee dates with Max. So he's not totally isolated.
There are many parents who wish they could stay at home while the kids are young. Who's to say once Gracie starts terrorizing preschool he won't look into getting a part-time job?
He has options. Staying at home with his kids is one of them and that's what he's chosen. Granted he knows he doesn't have any skills, but that doesn't mean he wouldn't be open to acquiring them once the kids are a little older.
Again, if Kyan were female, going back to school or learning a trade once the kids were in school wouldn't be an issue.
So even though I'm pissed at him for being a pain in the ass about this, I get where he's coming from. When you back an animal into a corner, they're gonna lash out. Just watch the teeth and claws.
Perry will be patient. Kyan will calm down.
Probably.
Maybe.
