But does the bad family marriage excuse the heartbreaker behavior? Cause I gotta say, it's not like anyone else's parents have good marriages on that show! B's parents are divorced, Willow doesn't seem to have a home life to speak of, Tara's family are creepy misogynist fundamentalists. Heck, Angel had major Issues with his daddy, and Spike vamped his mum. So they should all be coming from the same place as far as screwed up patterns comes from. And yeah, none of them are great shakes at making love last, but they don't o quite as far as Xander does into destroy all I touch territory, imo.
