Letting you go... (Spanish)

I have to let you go...

Little by little I adjusted to the fact that you were no longer mine, little by little I understood that you had stopped loving me and I understand it, I was immature and I was a fool many times because you wanted love and many times I denied it to you because I was at parties or doing business, forgive me, now I understand the phrase "you never know what you have until you lose it".
