Not sure if this really belongs here, but was the best fit I could find.
I worked for a company for 20+ years. Early on I worked as assistant to a man 10 years older than me who was just starting to become a high flyer. We worked well together, got on at work and had a very high regard for each other professionally, but there was never any hint of anything else. He outwardly appeared v confident (as high flyers do) and was often resented by his peers and other employees, but I always found him to be honest, straightforward and very uncertain of himself. We worked together 1 2 1 for about 5 years and I felt I knew him well (and him me). We talked about home and family, like you do, but I never met them, we weren't that close iyswim.
Over the years, we moved in separate directions, but from time to time our paths would cross and he twice employed me (within the same company) in positions that were good promotions for me. He became very senior indeed and there started to be rumours that some of his business dealings weren't quite straight and also of womanising. I always refused to believe any of it. The man I knew was completely honest and adored his wife and DC and that's what I told anyone who mentioned it in front of me.
Last year he left the organisation abruptly, apparently to take a too good to refuse offer elsewhere. Again eyebrows were raised about his reasons for going after 30ish years, I just felt pleased for him and that he deserved it, he'd done more than his bit for this company.
Anyway, this week he's been arrested for money-laundering after an internal inquiry that seems to leave no doubt that he's guilty as sin. (Obv not until proven, but still)
I am so upset by it. He talked to me about how he felt when others were unkind, about his health concerns and concern for his DC's development. When I wasn't working for him, he would occasionally call me for advice. I really thought he was one of the good guys and I feel so let down to have got it so wrong. Because of the way my career was very much linked to his, people are starting to wonder about me too, which is distressing. It's making me question my judgement about everyone I know.
