My best guess is that about twenty, twenty-five, years ago (the oblate spheroid is in her mid- to late 40s), the submarine skipper was at some luxury beachside resort on the western coast of Mexico, and ran into her. As the oblate spheroid was part of the 1% of Mexico, that's probably where one could find her.
And then maybe the oblate spheroid's mother put some sort of love-potion into the sailor's drink, and he drank.
And thus the marriage. She became an American citizen in either 1999 or 2000.
I've never gotten any clue the oblate spheroid's ever worked for a paycheck; it looks as if she was simply a seaman's stay-at-home wife, they living off his naval income, and then after he retired, they living off his naval retirement pension and his job at the post office.
The crazy bald dwarf has never worked even a single minute in her entire life.
All her fantasy careers in EMS, military, police, etc., are just that - fantasies.
My theory on her marriage to that addled ex-Navy non-comm is that it has to do with his submarine service.
I suspect that he encountered the nutcase immediately following a three-month submerged cruise, during which the boat's oxygen sensor was somehow defective.
His brain was permanently addled, while the normal urges of a sailor on leave after a long deployment at sea were unaffected.
In his addled state, he crossed the border from San Diego, bound for the Tijuana donkey shows.
Nutcase nadin, who was desperately searching for a way out of the shithole south of Texas that didn't include hiding under a load of watermelons, became that legendary "any port in a storm".
The permanently-addled sailor found momentary satisfaction in exchange for a lifetime in the company of a lunatic.
The crazy bald dwarf escaped to El Norte and a monthly U.S. government check for life.
That's what you call a "lose-win" proposition.
