I can't disagree. Interrupting is rude.
But I think I really did mean to overlap, not just stop my husband from talking. When I talk in this circular way with others who do it two, our talk really does run kind of together. I know it must work for some groups because personally, in groups of two or three where we do this together, I know we all feel "heard."
But my spouse did not feel heard, and therein lies the problem.
Thank you for the reminder not to do this with people who have a pattern more like yours. Mostly I am interested, particularly in hearing different viewpoints, so I really have to make that effort to overlap less with people who dislike it!
