Really? I'd like to see where that stat comes from. Sounds like something out of fantasy fiction if you ask me.
While I have no statistic to back it up (which is why I would never quote a percentage), real life observations suggest the percentage of marriages which survive transition is quite low.
So please, share where the 85% comes from so I can show my wife...and she could then promptly remind me that if I go there, I will most certainly be part of the 15%.
