43 years married plus we "lived in sin" for 5 years before getting married so we've been together for 48 years total. It's kinda funny... my wife's mother wasn't real happy about the living together thing for quite a while and then at the dinner table on Thanksgiving day a few years after we were married she said looking back at all of their friend's kids that had gotten divorced after a short marriage that maybe that living together first thing might not be such a bad idea after all.
I guess I should add that I was married for 7 torturous years to my high school sweetheart starting not long after graduating high school before stumbling across the real woman I'm happily married to now!
