Cool story, bro. Hope she wasn't married to a huge jealous linebacker who put you in traction.
OP-- I agree with EllieP. That is way out of line. Brother-in-law becomes your own brother, in my mind, so it's practically incest. It may be a good idea to tell her how much it offends you for her to entertain such thought of your lawfully wedded spouse. You wouldn't have such thoughts of her husband, would you? I hope not.
