I know, I was raised Catholic. Problem was that people stayed in horrible marriages because of the Church and society's prohibition on divorce. Unless there are some huge problems, people should stay married and grow up. My parents were chaste until marriage. They were quite older than most newlyweds, too. My oldest girl is getting married friday. Even though her and her fiancee live together, they are waiting for marriage. He's Hindu btw.
I know hundreds of Catholics from my parents generation and before who stayed married, and I know none that have the kind of marriage your talking about.
