in a relationship with healthy communication, arguments should end with understanding on both ends
you have to keep the goal in mind
do you want to win? or do you want to understand that person and resolve the issue? (ask yourself once, then ask again)
the ego loves to win an argument, but relationships are not about feeding your ego
healthy relationships dilute the ego
if you find yourself arguing to win in your relationship, consider what you value more: the love you share with that person, or protecting your ego
