Lyrics
I Still Have That Other Girl
I have to say that we should finish it now
Before we weaken 'cause we already know this is wrong
I could give in, sometimes I think that I will
Despite the temptation, I try to be very strong
In my reluctance seems a surprise
It's not 'cause I don't want you
But I just
Know I must hesitate
Because I still have that other girl in my head
I still have that other girl in my head
There may be ugly rumors that I have been lying
There may be angry tears, but they're never worth the crying
That is why
Sometimes I hesitate
Because I still have that other girl in my head
I still have that other girl in my head
I still have that other girl in my head
