It means when you marry someone, to a large extent you also marry that person's family. If your fiancée is not willing to set some firm boundaries with her mother - up to and including completely cutting her mom out of your lives if her mom doesn't shape up - you can expect more drama, heartache, and legal expenses as a result of Mom's actions. You both need to decide how that's going to be handled before you get married.
