I was told once that two good people will never hurt each other. Ok actually i was the one scared of a relationship that's when I was told this. Then it happened, I started loving him more and more as time went by and still do.
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.
