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!

Hello?
It's me amor, before you hang up, just let me explain...

Don't call me again, trying to explain
that what I saw wasn't true
You should be ashamed of yourself
for trying to convince me
that you're faithful and sincere
I saw you with her, you can't deny
that those were your lips that were kissing her
It didn't do you any good trying to pretend
that you were only chatting,
don't lie anymore

If you call me again, I'll hang up again
I'm already tired of hearing more excuses and lies
Don't call me again, I'm not going to forgive you
Another chance, I won't give you
You're not worth it
