what signs would this song be a relationsip about?

Return to Me - The October Project

You rise like a wave in the ocean

And you fall gently back to the sea

Now I want to know how to hold you

Return to me, return to me

You shine like the moon over water

And you darken the sky when you leave

Now I want to know how to keep you

Return to me, return to me, turn to me, return to me

Everything I tell you has been spoken

And everything I say was said before

But everything I feel is for the first time

And everything I feel, I feel for you

I am here calling the wind

I am here calling your name

I am here calling you back

Return to me, return to me

I know what it means to be lonely

And I know what it means to be free

Now I want to know how to love you

Return to me, return to me

I am here calling the wind

I am here calling your name

I am here calling you back

Return to me, return to me

I'm here return to me
