I have seen couples fight about who brought more baggage into the marriage, who left the refrigerator door open and other petty things. If you are fighting about who is more right, the argument will escalate and no one will ever win. Even if you think you won, you will feel bad because the other person is miserable.
Your relationship is guaranteed to suffer with escalating disagreements
If you find yourself in a similar situation, soften up, and lighten up. Think about the bigger picture:
Why are you with this person? What do you want your life together to be like?
Doing this will get you out of your head and give you access to the wisdom of your heart. And you will know what to do next. As you immediately shift your tone, you will have gotten out of that head of yours that wants to prove you're “right," and accessed a deeper truth within your heart and why you love this other person.
It might just save your relationship.
