As a romance author, I of course believe in happily ever after. But I don't particularly believe in the marriage. To me, it's just a piece of paper.
Here are some interesting quotes about marriage:
Marriage is a three ring circus: engagement ring, wedding ring, and suffering. - Anonymous
Love is blind -- marriage is the eye-opener. - Pauline Thomason
A good marriage is like a casserole, only those responsible for it really know what goes in it. - Anonymous
By taking a second wife he pays the highest compliment to the first, by showing that she made him so happy as a married man, that he wishes to be so a second time. - Samuel Johnson
Not that I agree with all of them but what do you think?
