The reason for that, is that I have personally witnessed supposedly "qualified" women change into the "courtesan-prostitute" you describe, once made aware of their power when aligned with the Court system.
I dont think it is possible to know one's true nature ahead of time. Every marriage is a crap-shoot, and while some get lucky, most do not.
Things were not always as they are today, so we have to ask ourselves what changed. I submit that what has changed are the legal system for women in America, and women's attitude towards men, with influence from the Feminists.
50 years ago, Men were a respected commodity, for which women sought fairly and earnestly. Nowadays, Men's MONEY is the only thing that is respected, and sought for many women, and they make no secret of this.
When the State colludes with women through their legal licences (marriage and birth certificates) to lay claim to a man's money without benefit of due process, or adherence to LAW, then men must avoid having their names on those licences which allow such behaviour to take place.
I respect your opinion, and welcome your response.
That last part isn't true. May be for some but not all. You should make that point. If you believe it.
