My problem is not making myself scarce when I see it coming.
You recognizing this I think is good. I used to sit there and take it because my W is good at "emphasis" - repeating over and over. So I would either, make myself scarce or only listen to one gyration and then go do something else. When on the phone this is easy - preface EVERY conversation with "I only have X minutes then I have to go do Y". This sets the expectation. When at home, that is more tricky so best to try and listen - then after the second reading of the riot act, simply say "I undertand what you are saying, now I have to go do X" or better yet, "If you are going to continue to repeating, this conversation is over". You have that right, as a man and she might just respect you for it. I've done this when my W has berated me - she get's really steamed at the moment - then a couple hours later, strangely she wants to jump my bones....
In other words, take control...not in an abusive way - but in a way that shows you won't be walked on.

Never sacrifice the great for the good. Sometimes the beauty of grace is that it makes life not fair.
