I married while an undergrad. She was sweet and a good companion. Before grad school we were no longer a good match by both our assessments. We divorce just before we both began our separate paths through grad school. Paupers, both of us, no kids, nothing to divide between us. In and out in 3 years. It was done.
During under grad and grad school (STEM) women simply did NOT like serious STEM geeks. Though I looked good enough in grad school I could not have bought a date even if I had had any money. While on my first job it was more of the same. ... He's a geek ... ewwwwwww.
Before I sold my company the GoldDiggers were bad enough. They would seek me out at conferences pretending to be there for the same reasons I was: business networking. They would follow me home from work, then wait until I went out for whatever just to see where I went. Then would show up there when they expected me to. The grocery store was the most common place for contact. A good looking woman approaches me at the grocery store, the odds were dead on she was a GoldDigger looking for a mark.
After I sold my company some of the same behavior by new GoldDiggers persisted. There must be a GoldDigger's network out there somewhere these cunts buy/swap/trade data on potential marks. -- The most recent tactic used by the persistent and I would add aging GoldDiggers is to drive to my house in the evening, park where they can see comings and goings (I do dinner parties fairly frequently) and identify people attending, get the license plate numbers from their cars, have someone with credentials look up their identities via vehicle registrations, manufacture a reason to befriend them, then use that to be invited along as "guest" to one of my parties. Once there she tries to hit on me. This has happened 3 times that I know of. -- I spent some money on a private investigator to vet some women who met some criteria I was provided as a "hint you are dealing with a GoldDigger" to weed some out directly and for others to pay for an investigation. It became a burden.
I ultimately gave up on finding a "keeper" and kept a few plates. The plates know a good thing when they see it and most moved for promotion to LTR quickly. Turnover was high. In the end I became MGTOW because the risk was not worth the exposure. Having found retirement activities that I enjoy and people to enjoy them with, the loneliness I first experienced after committing to MGTOW has faded to zero.
Dying along is not a worry. Were I to marry, become common law married or even LTR, I'd have to worry about dying along and broke.
