Threw a tantrum when her parents would not give her a car when she moved out
Would fly into a rage for the most inconsequential things
Would pick fights by pretending I had said something that I didn't, or would suddenly change things in the middle of an arguement
Just downright loved to argue, and claimed she could "win" any argument
Bragged about how she had been in the popular crowd back in high school, while shitting on my for not being popular when I was in HS. She seriously thought that being at the top of the HS pecking order was something you would be recognized for throughout life. Spoiler alert: I met her HS friends, and no way were these people the popular/cool crowd.
Poor personal hygiene.
Extremely materialistic. Demanded expensive gifts and scoffed what gifts I could afford to give her
Tricked me into driving her around the city to look at expensive apartments (more than she could afford) under the pretext of needing a new place. Meanwhile, she already having put a deposit on a place across the street from where she was living. Oh yeah, and I had finals that week.
