Ian says he was ready to walk down the aisle with his fiancée, Mel, whom he had been dating for six years, when his father advised him to get a prenup. After he heard rumors about Mel’s partying, drinking and possible cheating, Ian says he had an agreement drafted and presented it to his fiancée five weeks before the wedding.
