Learn how to argue-effectively.

Arguments are not necessarily bad-as long as you know how to do it right. Its wrong when arguments make you see each other as enemies: he did this so he’s to blame; she did that so she’s to blame.
You know you’re arguing the right way when you think:
“You know what we are husband and wife, we belong to the same team. Now lets see how we can team needing a different approach to disciplining our kids or (fill in the problem you’re facing here)”
When you argue this way, you realize that no one needs to be right or wrong and that you definitely are not enemies. Instead, you are allies, banding together on the same side, helping each other find a solution to the same problem.
In a marriage, when you try to prove how the other person is wrong, you might end up being right. But the marriage always loses-and so do you. If you learn to let go of your need to “be right,” learn to identify the real issue, and be humble enough to reach out to win: you, your spouse, and most especially, your marriage.
