I crashed my friend's BMW
I have an officemate/old friend who went to vacation in Hawaii. He's vacationing with his family and since we're good friends, I joked about borrowing his old sedan (a BMW 3 series). To my surprise, he said yes. So I drove it excitedly back to our house and I told my wife it was Brad's (my friend's).
I was supposed to return it a week after, and his sister who will be coming to his house will wait for it. But my wise wife decided to use it WITHOUT MY PERMISSION. SHE LATER SAID SHE WAS ONLY GONNA FLAUNT IT TO HER AMIGA. She crashed the car!! I am super furious even as I type this now! Because of her, my good friend was "turned off" because I couldn't take care of HIS CAR that I borrowed.
My wife and I are still not talking. I now have a nickname in our office and rumors are circulating about me, a guy who "borrows a BMW and crashes it because he doesn't know how to drive". As much as I'm angry, I want to resolve this conflict with my wife. But she has sky high ego and won't even fix her mistake and apologize properly. I can't believe I married someone like this. What should I do?
