W has told me I have this same problem. I am an engineer so I think a lot of that is built into me.
I'm not sure I have any good advice, other than "resisting the temptation" as you stated above. I've been working on that as well.... There have been several times since I've started working on 180s that she has said or done something that seems asinine to me but I've just bit my tongue and let it go. For instance:
W has smoke off and on since HS. She used Chantix to stop a few years ago and since then has only smoked socially (when having a drink or around others that smoke). Well she has been sick with a nasty cold and/or sinus infection for the last week or so. Last weekend we went (separately) to a little get-together at a friends house. The weather had been pleasant for several days but a strong cold front came through that day and it was very cold and windy that evening. W's sister, who smokes as a habit, was also there and they went outside to smoke several times throughout the evening. Seems like the smoking and the running in and out of the cold night air to do so would be some of the last things you would do if you were sick and hacking and coughing, and I sure wanted to tell her that. But I just gritted my teeth and didn't say anything to her about it. If I would have, I'm sure she would say that I was over-analyzing the sitch and trying to control her.
