i used to think communication was a key until i realized comprehension is. you can communicate all you want with someone but if they don’t understand you or refuse to understand, communication is useless.
You can go through all the heartbreak and no longer be in love with someone, but still feel that ache in your chest when something reminds you of them because deep down you'll never understand why you were treated so wrong when all you were trying to do was make them happy.
