OMG! Thank you for posting this, as I have found the exact same thing to be true. Be it on TV, or amongst my friends, vow renewals do not indicate a happy ending. After seeing so many of my friends' relationships end, I realized the vow renewal was a last ditch attempt to fix the relationship. When Jasmine of "Little Women..." fame announced a renewal, I immediately thought, here comes the separation. Public displays of love do not fix a broken relationship.
