That completely destroys my plans

I knew from the first I love you
And my heart was your to command
Now you tell me you think you love another
And that completely destroys my plans
So I told myself I'd forget you
And I'll do it just as fast as I can
Oh but I can't even take down your picture
And that completely destroys my plans

My plans were just to be happy but now I don't see how I can
For as long as someone else is there beside you
That completely destroys my plans
Yes as long as someone else is there beside you
That completely destroys my plans
