Your emotional life will not be somehow better or mere genuine by just letting it roam free without any guidance. Introspection and self criticism is useful to self improvments. I don't see how doing it systematically would be harmful.

The vast majority of my experience suggests that analysing important factors significantly improves decision making and radically improves the odds of a far superior outcome. Do you have any evidence that thinking carefully about how you feel makes one a bad husband? I would have thought just the opposite.
