I Don't Care (If You Don't Care For Me) lyrics

I tell myself that I must cry
It didn't hurt the day you said goodbye
'Cause I don't care
If you don't care for me.
Some other arms gonna hold you tight
Some other lips gonna kiss you every night
But I don't care
If you don't care for me.
I stopped remembering love that we knew
Now I've even stopped remembering you.
I know the part that I must play
Maybe I'll start believin'everything that I say
Then I won't care
If you won't care for me.
I must pretend so you'll never know
My heart is aching but it never will show.
I must believe it's over now
And learn to live my life again, somehow
Then I won't care
If you don't care for me...
