I was talking to my dad about divorce and they commented about the high rate of divorce amongst his age group.
I am actually surprised that it isn't higher given the 'typical' marriage pattern of baby-boomers. Very early marriages (my parents were engaged at 17 and married at 21 without having serious relationships with other people.)
They'd had no experience of living together or even being an independent adult - both moved straight from their parents homes to their marital home. Several of their friends 'had' to get married as the bride was pregnant (yet a surprising number of these marriages have lasted too)
Late teens seems absurdly young to pick your life partner, I couldn't pick a pair of socks to wear at that age. It seems that the 'typical' baby-boomer marriage was a bit of pot luck and keeping your fingers crossed for the best.
AIBU to be surprised that so many marriages made in these circumstances have turned out to be successful (or at the very least endured!)
