My ex did the house stuff too (although I worked with him in our remodels). He was the “expert” because he grew up in a construction family. During post-Dday stuff we had a doorknob on our front door that was broke. Old style no replacements avail. He did nothing about it. I realized the matching doorknob on the garage side door would match, took it off and replaced it in the front door. That was empowering.
Ex was also the “musician in the family” because he could play a dozen Neil young songs on acoustic guitar. After he left and I learned to play percussion I toured and played opening act in bills with famous headliners. I imagine him green with envy.
