Whatever they say about loving stuff and letting it go is wildly subjective and skewed into the letting-goers' favor.
      
      When someone's love and the love you have for them is your world, and they simply let you go, how can you ever come back?

Still I agree though, with what they say about living and loving. Life will have hard times regardless, so fill the other times with love. It will always be better to have lived and loved than to not have, no matter how vulnerable it leaves you each and every time.
