Would you be mad?😒

We often borrow SOs dads truck because hubby is in construction and we need to haul things. Well this time the car (MY car we share but in my name) was left at his dads house and he used it then let his daughter in law take it to work cuz she usually borrows one of their other cars. SO never even told me about it, and my cars still not back. He said I'm being crazy that the car will be fine but what the heck??? Why would you not tell me other ppl were using a car that's all in my name? The cars super important to me as I worked hard to get it, and it's the only asset we really have right now. 😣😩😭
