Okay I'm going to try and be as concise as possible without being too outing.
I am know the general consensus on MN is to stay out of these type of problems but it is honestly making me feel guilty by association and I just feel so sorry for this mans wife.
So the man in question hugely successful business man, hands in many pies so to speak and a real charmer.
His wife who owns 50% of the businesses and assets is one of the loveliest people I know.
He is where he is because of her, absolutely 100%.
For the past 4 months or so he has been having an affair with an employee who is recently out of a relationship. She knows he is married as the mans wife is also her boss and we live in a really small town. If you think of the film hot fuzz it is a lot like that 
He spends one evening a week there always the same night as he can legitimately be away. I know this but ( I'll be vague here as way too outing). They never go out and cover the car with a sheet.
What is really starting to bother me is that since she has been having an affair with this man she has a car worth around 6 times the amount of the car she had initially, she has been given an expenses card (again I can't say how I know this but I do) and she doesn't have a job within the company that requires a car or expense account. Far from it.
Yet the manager has made cuts to some of the small perks the company had because of losses since covid
Yet his bit on the side is driving around in a 70k brand new car.
I think the main thing that bothers me is that I know his wife and she is just so genuinely lovely.
I saw her the other week and she was upset that her and her husband couldnt go to an event they have gone to annually as he was so busy with work.
He did in fact go but took the other woman.
I feel like his wife is not only being cheated on but is essentially paying the wages of her husbands mistress (well 50% of them)
My DH thinks I'm silly to let it bother me but I cannot help it.
Aibu?
