Get You Own Girlfriend

It started off as fun, but
it got old real fast
Eventually it turned my stomach
I thought I'd let it slide,
but you had an idea
That I knew what I knew about it
I can't believe what's going on
You have the guts to say I'm wrong
You tried to pull the sheets right
up over my eyes But I can still see
through your lies
You knew how much I cared,
so why did you move in?
Why can't you just get your own girl
This ain't selfish of me,
what's mine it is not yours
You are not the friend I needed
