Well, according to that article, I'm doomed then. We've been together for almost 16 years! Personally, in MY opinion, it's a bunch of hooey.
FH and I were discussing our length of relationship just this weekend. We have friends who have been married from 2 - 50 years (and some dated for probably less than 3 years), and many of those relationships are on the rocks.
My FH and I have been through better or worse, for richer or poorer, and most recently in sickness and in health. You know what? Our relationship is stronger and more stable than 75% of married couples we know!
I don't feel bad about my decision to wait this long to get married, I don't believe that our marriage is doomed for divorce, and I certainly don't believe everything I read.
It certainly is an interesting article, but at the same time I think that there are so many so-called experts out there looking for a "cause" of divorce. Maybe they are looking in the wrong place?
