Our Fault in Love

I dont know
Why you can be in my life
In the past
You just like a ghost
Even if you were there
But i did'nt see you
And everything has changed
You made my life so gray
You came like you were alone
I knew you were not alone
But i was very stupid
With pleasure i accepted your attendance
I opened my heart to let you entered it
But i was still stupid
I realized, I was not alone too
But i kept let him to entered in my heart
This was our fault
We knew
You and me were not alone
But we kept to decided together
And again
This was our fault in love
Let us stop this situation
And being happy with our own
