Oh, and in the extremely small chance of a divorce (married men will give you various reasons why they will never get divorced - the chance is less than half a percent, in fact zero for them), she will get some of the proceeds of your hard work. Plus maybe some of the future proceeds, because a quirk of the American "justice" system is that the harder you work, and the less she worked, the more she gets. Cool.
And what really happens in divorces that is not recorded in statistics: She may get a 10% fee from the IRS for whistleblowing on all of your unreported income (that basically went to her). You may not only pay a negligence fee (and interest), if it is big enough you go to jail. She gets the reward. // She may get an undisclosed "settlement", if you have any interest in keeping a public reputation, in not writing an article for a magazine or a book or otherwise publicizing your sex habits and your penis size. // She will poison your relationships with her manipulation. // She will feel absolutely entitled to every penny you have, to the extent that you question yourself - because she is so sure of herself. // A common occurrence is that you may end up paying not only for her but for her biker bad-boy boyfriend that she moved in, who will also live off you. You never even expected that one. She's just not like that.
But keep working and working and working under your illusion.
