This guy is the definition of a deluded nice guy. When he finds out that he can't impose control over a very uncomfortable woman, he threatens to sue her. Sounds like someone never grew up and learned how the world works, and that sometimes you don't get what you want. But when you don't get what you want that is no excuse to start threatening people around you that you're going to sue.
Buckle up and brace yourself for this guy's full on meltdown.
