End before the start

I knew the end right before the start,
I don't know, I don't know, I don't know,
Again and always
But for how long?
It was a mistake, my personal mistake
To think someone like you could love someone like me,
I'm sorry, there's one thing you can do about that,
Forget about me, it won't be so hard,
I mean,
I thought I could do this, thought it could be you and me, but there'll always be just me, nobody who could see through the wall
