Every married person knows to be faithful, stay truthful and be there for her partner through good times and bad—they're in the wedding vows, after all. But most seasoned couples would admit that some unspoken rules are vital for getting past rough patches and growing stronger as a couple. Here, experts share 10 of the less apparent (but just as important) marriage rules to live by.

1. Don't criticize your partner's parents or friends.

You know how it is—your family can tick you off but no one else had dare speak ill of them. That's why you should tread carefully with your in-laws and your husband's dearest friends. "Even when he's venting to you, your contributions can put him on the defensive," explains LeslieBeth Wish, EdD, a Florida-based psychologist and licensed clinical social worker. "When you take position A, you prompt your partner to take position B." Instead, says Dr. Wish, put yourself in his position so that you can empathize with him.
