Famous Blue Raincoat Interpretation

Its early in the morning and I'm sitting here wide awake  
Jane's sound asleep and I can't help but think of you, my friend  
Out there trying to lose yourself  
Lose the pain that you are burdened with  
This addiction that eats at your soul  
 
Jane came over and she was wearing your shirt  
She took it to remember you  
She told me that you were trying to get clean  
Were you able to beat your demons?  
 
You had aged so much the last time I saw you  
The drugs seemed to ravage your body  
Your blue coat that you cherished  
Was tattered and filthy  
It was hard to see how you had let yourself go  
You were searching for the one who had your heart  
But you found Jane that night  
She was never the same woman after that  
 
She was so enthralled by you  
By your pain and suffering  
Your sadness reached her soul  
She speaks of you often  
 
The truth is, even though what happened destroyed me  
Even though I felt betrayed  
I miss you as much as she does  
She was never really mine  
You showed me that, whether intentionally or not  
I suppose that earns you my appreciation  
She may be here but she waits for you  
Ill fill the space while she hopes for your return  
 
You have my gratitude  
There was a longing and an emptiness in her eyes  
No matter how much I tried I could never fill it  
I stopped trying  
You took that away ever so briefly  
 
Jane came over and she was wearing your shirt  
She took it to remember you  
She told me that you were trying to get clean
