Where do broken hearts go?

Funny is...I've heard this question several times in the past few days. Made me realize...where "do" broken hearts go? if ever is there such a place? how to get there? Today its official... I have realized that the last person I was in a relationship with for the past 4 years, has moved on, he has erased me from his world, as if I never existed, Its just sad that after all the promises..it has come to this. This made me thinking...was he ever mine? was it even real? a lot of questions left unanswered... but I guess now, with what I have seen...its just simple...and the answer is staring me at the face. So yes, I am disappointed, broken, hurt and saddened. But I have to move on.
