This is what my father does throughout the day and it drives me up the wall. Out of nowhere, he'll blurt out an insult that me or my mother are both crazy nutjobs, etc. Or talk to himself about how crazy we are and how he can't wait to get away from us or get rid of me. He does this several times a day, EVERYDAY. When I'm home I try to wear headphones so I wont hear him. Talk about misery loves company. Is this typical behavior of someone with Borderline Personality Disorder?
My mother is completely resistant to it. It doesn't seem to phase her at all.
