Why would she?

Why did she do it?
She knew how I felt
Why did she do it?
Does she feel proud of herself?

He was mine at first
She knew
This was the second time
She’s done it to it isn’t new

She’s breaking my heart
And tearing us apart
She invited him over
With candles lit

It was only dinner his just a friend she had said
Why would she do
What I got told

she knows very well
how i still felt
why would she
let him sleep over
was it way past 12?

ok I can't think of anything now I've stuffed this up havn't I? anyone have any good ideas to fix it up?
