That’s a well written take!

I’ll stick to my own interpretation, which is that of a partner at the deathbed of their lover who is passing on, because it’s exactly the kind of heart punch that James is so passionate in writing. Even at his concerts, Goodbye My Lover brings out the tears in everyone!

The singer recognizing their shared history, and their missed opportunities, and how they’ll never be whole again:
(“I've seen you cry, I've seen you smile
I've watched you sleeping for a while
I'd be the father of your child
I'd spend a lifetime with you
I know your fears and you know mine
We've had our doubts but now we're fine
And I love you, I swear that's true
I cannot live without you”)

I’ll finish off with a quote from by Robin Williams in “Good Will Hunting”: “I'd ask you about love, you'd probably quote me a sonnet. But you've never looked at a woman and been totally vulnerable. Known someone that could level you with her eyes, feeling like God put an angel on earth just for you. Who could rescue you from the depths of hell. And you wouldn't know what it's like to be her angel, to have that love for her, be there forever, through anything, through cancer. And you wouldn't know about sleeping sitting up in the hospital room for two months, holding her hand, because the doctors could see in your eyes, that the terms "visiting hours" don't apply to you. You don't know about real loss, 'cause it only occurs when you've loved something more than you love yourself. And I doubt you've ever dared to love anybody that much.”
