Well said, Elicia, very well said. The tragic thing is, two thirds of married couples end up regretting the breakup, and I would like to bet what you say is the root cause of this.
So, they broke up not because the relationship wasn’t right, but because the situation was simply breaking them, and they couldn’t cope with it. The breakup helps them better cope perhaps because they can't use each other as figurative punch bags to take their frustrations out on any longer, but at the same time, it creates another world of even greater isolation.
Even if a coparenting arrangement is agreed, and adhered to properly, it typically means the kid goes from one isolated household to another on a regular basis.
That means an isolated world, has been made even more isolated. So everyone is in an even greater state of isolation than they already were. But the parents can at least cope with it better because they can't take out their frustrations at this isolation on each other.
It's a tragedy, the whole thing. So easily addressed as well if the government would just take action.
