Been trying to figure what this song is:

Here I sit alone
I stopped lying to myself
It feels like there's no reason
Now that you're gone
I lay in my bed with tears in my eyes
I really do love you
So won't you come back to me again

Cause I remember
When we made sweet love
Under the moonlit sky
And I remember when we feel in love
But so much has happened since then
And I need you back again

You know I shouldn't be alone..(Alone)
You left me here by myself
You know I shouldn't be alone..(Alone)
You left me here by myself
You know I shouldn't be alone..(Alone)

You left me all alone
Found a life of your own
And I hear that your doing fine
You only used to dream about
I miss you so much
Why did you stay away for so long
I miss you so much
Your all I think about

Cause I remember
When we made sweet love
Under the moonlit sky
And I remember when we feel in love
But so much has happened since then
And I need you back again

You know I shouldn't be alone..(Alone)
You left me here by myself
You know I shouldn't be alone..(Alone)
You left me here by myself
You know I shouldn't be alone..(Alone)
