Just watched "War dogs" (loved it btw) and there is a subplot (if you want to avoid spoilers just move to the second paragraph), where the wife of the protagonist finds out that he is a gun dealer, they have a number of fights because of it and she ends up dumping him. And the whole situation, when the guy was jerking people off for a living, barely making the ends meet, then becomes gun dealer, buys porshe, luxurious apartment, finds actual excitement in his job and get dumped as a result feels so unrealistic to me. Most girls I know would express only curiosity and excitement when the talk hovers over some shady business, I cant even imagine any of them dropping a guy after finding a fat stack of cash in their apartment.

Do you think that common movie trope when the girl dumps the guy after finding out that he is doing some highly profitable and exciting, but morally wrong/questionable business is based in reality? How common is such behaviour in real life in your opinion?
