Way to go, bebop! My brother and sister-in-law are in their combined eighth marriage :-) Each is the fourth spouse of the other and they couldn't be happier and in a better place for both of them (they're 65).
It's curious reading the women's side of multiple marriage and being a second wife (my first marriage) and thinking about the differences in attitudes between my husband and his first wife. I think women are much harder on themselves, even when it wasn't their or "anyone's" mistake really that a marriage broke up. Women seem to me to want and expect it to be "perfect" and are disappointed more often.
Leslie, I dated my husband 5 years before we married :-) We didn't get married (my first!) until I was 39 either. It was a very comfortable dating period.
