Why do we men give a damn about her state of mind?

I see it everyday here on askMRP from other OP's, and I'm no different.

Yesterday wife was distant and cool toward me most of the day (later discovered due to low level dread she's feeling - yesss!).

I did a better job of using /u/BluepillProfessor 's "Extinction" method of ignoring her negative behavior and rewarding her positive behavior. I managed to hold frame pretty damn well and be lighthearted in spite of her negative vibe.

But.

Every single time I was met with her coolness I would be in turmoil inside that she wasn't "happy" for lack of a better overall term. My emotions covered angry, curious, resentful, confused, etc. etc. etc.

Why? WHY?!? At this point in our piss poor marriages why do we give so many fucks?
