My first romance novel, while still entertaining to me, still has some truly brain - hurty moments.
I'm pretty sure that if a man asks his brothers - in - law for advice on the woman he's being forced to marry (historical romance) because she's annoying him and, from his perspective, being a bit of a shrew, his brothers - in - law are probably not going to say, "Eh, get married to her. It couldn't hurt - maybe the woman will be good for you." Um, what? If the woman is completely odious to him, I'm pretty sure that "it couldn't hurt" is not the best answer.
I could think of many other things to say: "Tough luck, old boy" or "Are you really sure she's that odious?" come to mind, not "Oh, that annoying person is a good wife for you because she has money! I'm sure that my advice won't totally backfire and put you in a hellish marriage, hating yourself, your wife, and the people who suggested you marry this woman!"
