oranges2apples: i didn't meen to quote you, but now that i'm here, how long does any relationship last. my last we had a 4 year difference ,i was older, we lasted 14 years.
Ok, and as you did quote me in the end, I actually meant that a really wide age difference does not, in my experience or opinion lead to longevity in a relationship.
Yes of course there are no guarantees in any relationship, but big age differences simply serve to magnify any problems.
I had problems occasionally with my ex husband during our twenty odd years together and he is only 9 years older!
