"I'm With You"
Please remember! This translation is my personal work It is sometimes difficult to translate word for word from Spanish to English, so it may sound awkward in one languange when it is perfectly natural in the other But I think you can get the general idea!

I'm with you for an eternity
There's nothing that can separate
this love that I feel in my being
that nobody will ever take away from me
And if one day you want to see me cry
You only have to say that you're leaving
Yes, I'll cry, and I'll also scream
if you scorn the love that I gave you
But that's not going to happen
Because I've settled (on a decision)
that my love is for you
And nothing could separate me from you
The love inside of me
that I feel for you
that nobody will ever take away from me
