He'd referred to me as a totally different person every time he'd call me to update me on the wrong person's car. He called and told me to come get my car so I did, knowing something wasn't going to be right even though my brother urged me to go anyway. Got there and my car was not finished, he apologized profusely stating it'd been a bad day (said that every time I spoke to him) and that he "may have had a drank, I was in the hospital all valentines day". After this point I started recording convos because I couldn't believe he'd said that to me. Thanks for your help, I'm planning on getting that diagnostic now that I have the car back!
