Not saying it was or is impossible... but still unlikely given what I know.
Before the lockdowns no sex. During the lockdowns sex. After the lockdowns no sex. I would be suspicious.
before the lockdowns a once a year affair, sex during the lockdowns, increased to a whopping 4x's after I had 2 extra STI tests to confirm I didn't have anything else over those 2 months (May and June). back to the once a year thing in 2021, and nothing now since that July 2021.
When I was having an affair with a married woman she used to find all kinds of creative ways to get out of the house.
And in the beginning car sex was all we had, it took me a few years to convince her to use a motel.
But at the beginning she was just more comfortable in her own mind to meet up somewhere between are houses (Green Acres mall was a favorite) and fuck in one of our cars.
A lot of times she would drop her son's off somewhere and I'd meet her near by and she'd jump in my car and I'd dump a load in her.
It sounds like based on your timeline, that this occurred more when cell phones and GPS weren't as ubiquitous... Much of current technology pretty much prevents this - even if my wife could spoof GPS, or disable the GPS tracking in Google Maps - I know how to do both and don't bother to even hide my own misdeeds (not worth all the extra effort and time over the convenance of having the history when I am trying to recall who I've seen where, or more importantly where have I eaten at nearby good restaurants when I can't recall the name), even the old style GPS/surveillance of early Google Maps timelines would have been a weakness -
I work in tech (and not 1st level help desk, all my work has been in coding, development, deployment and surveillance) so it also unfortunately pretty much it goes without saying that by default I am the resident tech guy/help desk for the entire family - and spend much of my time Google'ing how to's for the Help Desk issues.
Google Maps timeline is your friend or could be your worst enemy (thankfully my wife isn't really aware of it - before I mongered I used to try and show her how it worked so that as our kids got older we could monitor where they are... she gave up on it and made it my job to do, and now she just forces the kids to use Life360 (its easier for her). I've kept up with the app tech, just so that i can know the work arounds if my kids start creating the "Finsta" accounts -which has been used to my benefit in the mongering Finsta life. Nothign in tech leaves you fully anonymous, but it can be managed and minimized when you are catering to specific scenarios. In my case hiding from the wife my mongering activities higher priority then police (who are more likely to catch me in an AMP with my pants down than be in a sting - I don't do drugs or "trade" cash only at the meet, etc - keeping to the 1 crime at a time bible.
aside from the tech, she also would have had to really managed and convinced the then 4, 6 and 7 year olds to never tell daddy about any of the possible "uncle Joe's", those of you with kids know keeping secrets it is nearly impossible at that age. Now that they are teens, its possible that they may help mommy out, but still unlikely.
As using the kids sports, to hide meet-ups (I do do this as well, but I arrange incalls/carfun with the nearby talent no way I am taking any chances of my wife finding out because of Betty at practice accidentally says something in from of my wife outing me). My wife took to the socializing with all the other sports mom's that took to the kavitching on the fields and in the lobbies, and back then we were not even a dead bedroom yet - then a few years later and now I commute with some of those same mom's who returned to work (after stay at home life ended or worked nearby) on the LIRR (for the better higher paying city jobs), and the stories I hear from these women pretty much precludes it was happening; but still with the caveat it is possible.
So with 3 kids, all running in 3 different directions, when I am home I will help out and do these drop-off/pick-up times, and I don't even have time to do a short stay. My truck died just before the Lockdowns, and never bought a replacement, so we have been a single car family for almost 3 1/2 years now; making mongering more difficult for me - I used to do a lot in the City on my "lunch hour", now its all late evening, I forgot something to go to Home Depot... which I can add time by claiming store out of stock of, but it is at the next one nearby (giving me the extra time to meet)... but at the same time making it "
nearly" impossible (though
not impossible) for her to disappear either
