A narcissist
Narcissists are like the worst roommates. They think they're perfect, they lie to everyone, and they make you question your own sanity just so they can stay in control.
They blamed me for the leak in the ceiling even though I had no idea what was going on.
They said I was the one who started the fight, even though they were the one who threw the first punch.
They told me I was being dramatic for getting upset over their bad driving.
