Congrat!
With the percentages of success the way they are, you've got some nerve. It's almost like saying hey the odds of rolling your T4R up that climb are darn good, but hey there's a slight chance you might make it, and you take it. Well maybe not, but you get the point. I've been married 10 with her for 14, and it's been rough, but it's been great too. Too bad the rough side has been the more recent.
I heard on the radio that people are changing the normal vows of to death do us part. They said they have been changing them to for as long as our love will last, etc. I guess people are looking a marriage as something more temporary than before.
I think marriage works best when your wife is your best friend. You share hobbies, interest, etc. For the ones that are oil and water, and believe opposites attrack, get out of town. Those are the one's that don't last the long haul. At least in my experience.
