Yes, this is for super mature people, you fight many times, argue and even disturb your neighbors. These steps will work for you.
Pause
Rather than letting that fire escalate, let it die down by pausing, take deep breaths, don’t talk, and just think about what has happened.
Hold hands
It’s impossible to be mad at him if you’re holding hands. Hold hands for some moments, look into each other’s eyes and just try to see that person you fell in love with, not the person you’re arguing with.
Embrace
Embrace your loved one for a heart-to-heart hug, close your eyes and breathe deeply. Match the tempo of your breath with theirs, and be conscious of the fact that you both are alive.
Think about when you will be 200 years from now
How does it feel to know that you both will be gone soon, and you’ll leave this planet for good? Take a breath for 20 seconds, think deeply about what happens when you both are no longer here, and that’ll help you appreciate the fact that you both are alive, it’ll help you appreciate them and you’d want to make each moment you spend with them count.
