KNOW YOUR VALUE
When someone treats you like you're just one of many options, help them narrow their choice by removing yourself from the equation.
Sometimes you have to try not to care, no matter how much you do, Because sometimes you can mean almost nothing to someone who means so much to you.
it's not pride -it's self respect. Don't give part-time people full-time position in your life.
Know your value and what you have to offer, and never settle for anything less than what you deserve.
