Get out of my life

Why can't you just leave me alone
accept that I'm happy without you
putting me down, putting him down
none of that is going to bring me back
because I'm not ever coming back
there's nothing you can say
and there's nothing you can do
I'm not changing my mind
so just accept that we're through
get over it all and leave
I can't stand all your negativity
I don't need that in my life
I don't need you in my life
you're nothing but a virus
that keeps trying to infect me
but I've built up antibodies
I'm immune to your disease
I won't play your games
I see right through your lies
so move on and get out of my life
