The question

My controlling boyfriend had me pick up his car that was serviced at a mechanic shop and leave mine. I only wanted an oil change and my ac looked at to see why it was blowing hot. I never spoke to the mechanic and im the only one on the title. Well my boyfriend had $2000 worth of repairs done to my car without my consent or authorization. Ive been without my car for over a month now cause they want me to pay 2000 for repairs I NEVER WANTED IN THE FIRST PLACE. He knew he didnt have that kind of money right now so he did that so I wouldnt have my car.
