It is amazing how well the marriage industry sells the notion of the big day leading to a "happily ever after" ending. In spite of the 50 percent divorce rate, many people walk down the aisle believing in the sharply honed, expensively packaged, marketing message.
So maybe you should have a discussion concerning a prenuptial agreement and asset division prior to your marriage. Won't this poison the well? It is true discussions of a prenuptial agreement must be done with great sensitivity, they need not kill of any hope of a happy ending to your wedding day.
