Alice and Bob got together, they got engaged, and they got married. Everyone expects that they'll live Happily Ever After and grow old together. Then the news is broken that Alice and Bob are getting a divorce, even though they haven't even been married 5 years. What happened? Reasons for the divorce vary: one or both of them lacked maturity to sustain a long-term relationship, Alice and Bob had radically different goals and ideals in life, flaws (big or small) that they overlooked are coming to light, they married for the wrong reasons and/or too early. Whatever the reason(s) given, the marriage lasts less than 5 years, and generally the couple in question has no children together. It is also always a first marriage for at least one half of the couple, and very often both of them. May be the result of Relationship Writing Fumble, Alice and Bob being Strangled by the Red String, or simply the idea that True Love Is Boring. It may be used to prevent Shipping Bed Death. Compare Sex Changes Everything. Truth in Television, sadly.
