Officially annoyed with my MIL

By SO has been looking for a job because he got laid off and there was a job fair today and we asked his mom if we could borrow the car to go (it's really his car but she's paid the bill for the past month while he's out of work) and she said no because she had to go to the next  big city over and didn't want to put miles on her BF's truck but they decided not to go after all because "her bf didn't feel like going anywhere today" 🙄 So he missed the job fair of course. I'm starting to think she doesn't want him to ever get a job and just wants us to live with her forever.
