I had purchased upgraded front brakes for my motorcycle to a dual disc set up. The cost was nearly $1k. My justification was that my brake pads and rotors would last longer and give me better control (previously I was replacing the brake rotor annually, brake pads twice a year, and the brakes had a very wooden feel at the lever). My ******* coworker told her that I was just pissing away money and needed little more than better brake pads.
I got the silent treatment for months. It was a quiet couple months with the occasional look that kills! The only good thing that came out of it is that she learned not to pull that silent treatment game with me.
Ten years later I'm still on those rotors and have only replaced the pads a couple times. Most importantly I've had far less "oh shoot" experiences while braking hard.
You got to draw a line. No matter how much you love them, you can't let them start telling you what to do with your motorcycles.
