My husband has the same hook. He likes to imply that I'm doing something I shouldn't or seeing someone else. I haven't figured out the right "escape line" yet. If I shut him down & won't talk about it, then I'm covering something up. If I do talk about it, then I'm drawn into hours of draining emotional talk over something stupid that he won't even remember tomorrow. For now, the only somewhat safe escape I've found is to brush it off with a quick comment & then pretend I'm using the bathroom, putting kids to bed, etc.. until he gets distracted.
