Two sides to the door

Torn in two
Once again
With the one I loved before
And my best friend

I gave her a chance
She acted too slow
Now I wonder if i should stay
Or if maybe i should go

I'm with him now
And happy once more
But he doesn't really see
Theres two sides to this door

In love with them both
It's hard to choose
But I know either way
i would eventually lose...
