1) No one "has to" put up with any kind of partner. They choose to.
2) How about sympathizing with the people who deal with partners like the man in this story? Yeah, she gets way overly worked up over it, but how is, "It's nothing, don't worry about it" better than just telling her what's on his mind? It may not be hugely important, but obviously it's a big enough deal to keep his mind on it and she's noticed and asked, so why not just answer?? Even though her reaction is over-the-top, his response is not part of an open, honest relationship that lends itself to making the participants feel liked a trusted part of a team.
