Are We Supposed To Be US?

How can you just fake a smile,
How can I force a laugh?
Why do we bother faking thse things,
When we know we're each other's half?

When we know we're supposed to be together,
But our others pull us apart,
How can we not pull things together,
And put them back as they were in the start?

We're taking the long way down,
Our lives look so small,
I know we should be with each other,
But it just had to fall.

Can it be true that mine shouldn't be mine,
And that he isn't supposed to claim me as his?
How is it that we're so close but so far apart,
And you're the one I need to kiss?

I'm as confused as the next person,
Because I don't even know if I love him,
Thinking about you shouldn't even come to mind,
It only makes my head spin.

Everything has fallen through,
And that's why I'm with him,
That's why you're with her,
And thinking about you should be a sin.

I miss being us,
But somehow we're not together,
I still want to know if I can love him like I do you,
Of that I am not sure...
