Never go back! And if what broke you tries reaching out to you again, ignore them. A valuable lesson for everyone to know. If they broke you to begin with then he didn't love to fight and be better for both of you.
Take time to do what makes your soul happy.tapping into that part of you will nourish all other aspects of your life. Take the time. Revel in that time. And remember that time when not able to take that time ;D
