One impression I have of SS1988 is that English is not his first language, so maybe he is an immigrant. Maybe his future wife was a family friend, or someone his family later selected for him to marry. (Arranged marriages are still the norm in many cultures, even today.) Or it's a clue SS1988 made it all up.
One thing to keep in mind is that SS1988 knew her when she first arrived in Irving, a period of time when we have no clues where LEK was living. Even if SS1988 can be believed, the name we know her by would not appear anywhere. The house was in her mother's name, & she was still using her birth name.
If her mother was on Medicare or Medicaid, they'd take of all of the medical bills. When my grandmother died in 1992, that was how her medical bills were handled. Which left a few thousand dollars in CDs & her house (owned free & clear, but in need of a lot of work) for my sister & I to inherit. It didn't make either of us rich, but I did end up with enough money to make a down payment on a much better house in a less fancy part of town. So I could believe it possible LEK came into enough money that she didn't need to work for a while, if she lived frugally -- which would explain why she was off the radar for the first few years she lived in the Houston area. (And my masculine intuition leads me to believe LEK was someone who, if she didn't need to work wouldn't. She just didn't like to interact with other people.)
To repeat one of my talking points, we really don't know if LEK was a dancer/stripper. All we know is an ex-boyfriend said he heard she had done that for a while, & that she had breast implants. (And there are other reasons to get breast implants than to work in the sex industry.) The one job we knew she held at this time was "data entry", because she put that on her passport. I figure she was working a lot of temp jobs, which are often 9-5 (or were when I was a temp worker back in the 1980s), & that's how she & SS1988 met.
This reflects some of the effort required to believe what SS1988 told us. Maybe it's special pleading -- that is, asking us to accept a lot of involved arguments to believe what he posted -- which means its all B.S. And even after trying to answer your reasonable objections, I know I haven't been completely convincing; I'm still puzzled about how his wife came to know LEK, & not convinced I have the right answer. My own feeling is SS1988 probably is telling the truth (I'd give it a 60% chance), but I wouldn't use anything SS1988 told us to base a theory about her on.
