The contrived marital fights in TV shows all stem from the same situation: someone kept something from someone else for a "good" reason. As you watch these shows, you realize that the entire episode or series could have been resolved in a couple hours if the characters were honest and communicative. That is the gist of this marriage advice.
Try to approach things from your partners' perspective. Remember that what he or she says is most likely motivated by their own hurt. So it's important to not take it personally and instead approach it as a problem to solve. In fact, you should approach all arguments as an opportunity to resolve an issue. You and your spouse will disagree; it is healthy to disagree. Arguments are an opportunity for you to hash out these differences and hopefully come to a compromise.
Speaking of compromise, don't put off a resolution to issues between you and your spouse. Ignoring problems doesn't mean they go away. The more you put off, the more they pile up until you have a big fight that is too complicated to resolve.
Finally, pay attention to your tone, body language and facial expressions. How you say something is just as important what you say.
Tips, advice and open communication can only take a marriage so far. Sometimes, it just isn't enough. In those situations, you may want to speak to an attorney. A family law attorney can go over your options and help you formulate a plan.
