she didnt really break anything down
men have never been in the house like that till recently...
the most important thing children need from their father is a good stable upbringing (money), knowing that father loves them, knowing they can reach him whenever and that father to be a good example for them
I cant say Cam is all of that...
but if that Dr. believed everything she said then she should also believe getting a divorce should be more difficult than it already is
The nuclear family is a recent invention. Prior to the industrial revolution(approx 250 years ago) humans were mostly farmers.
This meant that men plowed the fields with their sons while the women might extract eggs, milk, or fur from the animals. Men might hand deliver the calf or plant the seeds in the soil while women would preserve the byproducts of the animals and fruits from the plants.
They would do all of these tasks as a family unit, each doing what they can. The wife would step in for the husband if he was injured, ill, or too old to continue doing certain tasks if she had the strength to do so.
This whole "I go and work away from my house and can be a slob that doesn't clean up after himself or cook, while my wife sits around at home cleaning up after me and my children and cooking for all of us" setup is new and only existed for less than 100 years. In the early 20th century, women were expected to clock in at the factory too and the kids were expected to do so as well as soon as they were old enough to understand instructions. Literally the whole family worked.
This new era of family where men are out here running around sleeping with women then bouncing after a baby is produced is new. Even if you want to make the comparison to ancient royalty(a bad example since people generally hated their kings and queens) they still made sure their kids grew up in the same household as them regardless of if they were from his original wife whom he has an actual relationship or his consorts( used as breeding stock, he has zero emotional attachment to them).
His behavior is irresponsible and I'm glad she called him out on this. Children deserve a home where they can see their mother and father interacting. It forms their first blueprint for what a couple should be and informs their relationship choices for the rest of their life. If you're not in the home of a child you created full time, another man is. Willingly letting another man raise your child is not masculine.
