Yes, it is your fault for losing or breaking your own property. Take some responsibility. When I moved to a phone without a headphone jack while driving a car that I plug my phone in via headphone jack, I simply kept the adapter plugged in to the cable in the car. It never broke. It never got lost. It stayed there until I got a Bluetooth head unit.

I’ve still got it in a drawer ready for if I ever needed it again, but since I’m not an audiophile with a $10k+ sound system listening to FLACs from my phone I don’t need it.
