The terror in American marriage for men, is that the woman can, and will move on, at the drop of a hat, penalty free, and rewarded as much as is possible.
The man loses everything, the woman merely gets rid of the “man”.
For the woman, things can stay exactly the same, the same house, the furniture, the laughing children, the PTA and teacher meetings, the schools and the little league.
You, however, seem to know women really well and are terrified of them.
