Dysfunctional; my parents divorced when I was 8 because my dad was a repeatedly unemployed alcoholic chain smoker who lied about money and almost lost us the house because he didn't pay the mortgage. My sisters were much older than me, so I never got to know them particularly well, and they weren't around much after the divorce. Between the ages of 4 and 8, I saw very little of either parent, since dad would be out or sitting in front of the TV smoking, and mum was working and trying to keep things running when she got back, and then would listen to relaxation tapes and get ill a lot.
After the divorce, I lived with mum, and the sisters moved away to go to uni. She worked a lot, and found some guy who was a dick and would manipulate her and periodically leave her and make her cry and stuff. He turned out to be a complete liar; he made up everything from where he'd grown up to what his job had been, and she found out just recently when she traced his family tree. She's still with him though.
