I know many people at 66 who would do anything to be able to separate from their spouse. Many do and end up in worse shape than never marrying at all.

Marriage is not some kind of guarantee against loneliness.

thing of it is this: Feminism changed gender relationships radically. Women foolishly believed that they could gain rights (at the expense of men) without having a change in behavior and attitude from men. Men also liberated themselves. They liberated themselves from the traditional responsibilities towards women. They no longer are required to marry, to procreate, or even to treat women with the kind of respect they expected in a traditional environment. These attitudes will absolutely continue. Women gained nothing through Feminism, if anything they lost a great deal. They are now something like prostitutes where they were once wives and mothers.
