Turn my back on you

I turn my back on you
Cause that's exactly what you would do.
All this time you made me believe
That you had turned a new leaf.
I now realise I was being stupid
For thinking it was all the work of Cupid.
I should've known better
When you acted like I didn't matter.
I should've left you earlier
But I thought with you I would be merrier.
It was stupid of me
That, now I see.
So now I turn my back on you
Cause I now want to be someone new.
