Maybe the guy realizes the courts are stacked against men if the marriage fails and children are involved.
Perhaps he wants to avoid the trap.
Maybe he realizes that the driven woman may want a child as an acccesory and not as a precious gift from God that requires placing the child in front of her “needs.”
Just a thought.
Most modern american women wont put their husbands needs before theirs. If a guy can sense this he may wonder if she will place the childs before hers. And if she does, now hes third in line, if he ever was in line to begin with.
