In all seriousness, I would have to say that the secret to a long standing relationship is actually liking the person you're with. You could love them to bits and have a great physical relationship but unless you like the person, it'll not be a happy union.
I was married before, and have only been with my OH for three years. We love each other and we like spending time together. There's not an hour goes by that I don't think about what he's doing and I know the same goes for him.
Ok, enough from me, this soppy behaviour is spoiling my reputation!!!!!!!
