My dear _Doncella, parts of the lyrics you posted make no sense whatsoever in Spanish. So I thought the one who wrote them down didn't understand them correctly. But: surprise! The band sings it wrong! As I gathered from the comments posted on youtube, the members of Alacranes Musical are quite...uneducated (so to say), so they didn't even bother to check the lyrics they were singing.
So I've made some searching and I found the original version of the song, by Valentin Elizalde and that's the one I am going to translate.
VETE YA
Go now!
SI NO ENCUENTRAS MOTIVOS
If you can't find reasons
PARA SEGUIR CONMIGO
to continue being with me
PARA QUE CONTINUAR
why should we go on
ES MEJOR
it's better
TERMINAR COMO AMIGOS
to end it being friends
QUE SER COMO ENEMIGOS
rather than being enemies
ESPERANDO ATACAR
waiting to attack.
CORO:
VETE SI NO SIENTES
Go, if you don't feel
QUE MI BOCA TE PROVOCA
that my mouth gives you
SENSACIONES CUANDO RONDA POR
sensations when it gets close to
TUS LABIOS
your lips
VETE SI TU CUERPO NO SE EXcITA
Go if your body doesn't get aroused
CUANDO EN FORMA DE CARICIAS
when by caressing you
TE RECORRO CON MIS MANOS
I go over your body with my hands
NADA JUSTIFICA EN ESTA VIDA
Nothing justifies in this life
SOPORTAR CON LA MENTIRA
Supporting with lies
UNA RELACION SI NO HAY AMOR
a relationship if love doesn't exist
VETE YA, SI NO HAY AMOR
go now, if love doesn't exist
VETE YA
Go now!
SI NO ENCUENTRAS MOTIVOS
If you can't find reasons
PARA SEGUIR CONMIGO
to continue being with me
PARA QUE CONTINUAR
why should we go on
ES MEJOR
it's better
TERMINAR COMO AMIGOS
to end it being friends
QUE SER COMO ENEMIGOS
rather than being enemies
ESPERANDO ATACAR
waiting to attack.
Enjoy the lyrics as they are quite beautiful
