Where are the keys to a successful marriage? Here, Sunniva Lia exposes some ways to deepen your relationship and make your marriage successful, especially when things seem to be going wrong. 1, Know that punishing each other is futile. Making the other person feel bad may make you feel better, but in reality, it will only make them more stuck. A better approach is to reward the parts you like and ignore the parts you don't like. 2, Money is the root cause of conflicts between both sides. To have a successful marriage, you need to clarify your financial situation and prepare a budget in advance. 3, If you do not evenly distribute household chores, friction will occur in your interactions.
