only almost here

Haven't I always loved you?

But when I need you
You're almost here
And I know that's not enough.
And when I'm with you
I'm close to tears
Because you're only almost here.

Isn't it sad how you can be with someone but still feel lonely? How they say that love is all that matters but it isn't? How sometimes, you can love someone with all your heart only to have them walk away, because they don't love you enough in return?
