The Way We Used To Be

We're just not the same as we used to be.
Tell me what your thinking
Tell me what your feeling
Why can't we just go back to being how we used to be?
you used to tell me you loved me, and I could tell that you meant it
Now when you tell me
I'm not too sure it's true
All this makes me second-guess the way I feel about you
Why can't we go back to being the way we used to be?
