If the break up was mutual then there really shouldn’t be a heartbroken one. Other than that, my only advice is to move on & fast. They did. They chose to be without you. & so, this is your chance to better yourself because if losing them caused you to truly BREAK your heart, you lost yourself. See this as an opportunity to better yourself cause let’s face it, you’re at your lowest if someone else was holding your happiness; the only option you have is to be better. As far as I’m concerned, you’re single now. So the only person you need to worry about is yourself. Don’t go all lone, bitter wolf, but understand & believe that you are in control. Once you do so, you will be at peace in any given situation, no matter how bothersome. 

Heartbroken is such a harsh word to me; I get hurt, devastated, but broken? It’s almost as if you ‘re giving the possibility that it can’t be fixed. People can always be fixed. If you just stop over thinking & over analyzing, every thing will be everything you need them to be.

I don’t know if that was any help.. I had a more intense response typed out but then I realized it was more of a response to “advice if you’re the one cheated on..”. Oooh boy, I fucking go off on that one hahah. But that. That’s my advice. Hope it helped.
