I saw this so often when I was client facing. CEOs, doctors, and sales people were the biggest offenders.
We had a gyno who had a huge pile of porn on his file server. It was all from the waist up. Seriously, he had half a terabyte of titty pics.
Separately, there was a sales guy who was juggling like 5 women (poorly) at any given time. He was fucking gross and would try to show them off to anyone who came to work on his continuous computer problems that were all caused by him.
Separately from that, we had a “troubled boys ranch” as one of our clients. One of the C Suite was caught with porn and we had to go over it with a fine toothed comb to make sure none of it was of any of the kids. There wasn’t (thankfully) but there was a whole lawsuit about it and he was charged with showing it to some of the kids.
Same here, and for approximately the same reason (I left her because of the broken trust, she tried to get me back with a plan to fuck with me but I was already too fucked up over it).
It wasn’t my final relationship, but I’ll die alone and pretty happy. I have a couple of people that I actually trust and, same as you, a butt load of acquaintances that I enjoy being around. I generally use “friend” as shorthand for those people, but they’ll never really know me.
I’m very up front about relationships having a shelf life.
