So much time that has passed
And to see everything that we dreamed may someday be already finished
This line presents ambiguity
It hurts me to think that what I wanted I don't have it by your side anymore
That has me so frustrated
And I can't endure anymore the desire to tell her
Or: And I can no longer bear the desire to tell her
I want to tell you that I love you
That despite that time passes, I miss you more
'A pesar' is an expression which roughly translates to 'despite' / 'in spite of'
That I'm still alone and that your absence hurts me
