Oh Axa.
I'm very sorry. I've been there and felt all the emptiness and shock and fear...
I am alone now and safe. I didn't know that I had a good friend growing inside myself.
I can't say it better than what's been said here...it does not have meaning who left first, hon.
Deal with the ending, the passage of this relationship. Not who closed a door and turned a back. That doesn't mean anything except that the last dramatic gesture this person turned his back and closed the door. It has no meaning. Let him have it.
You were here, in life, in yourself, before you even met him, and before he chose to walk away, and you will be here tomorrow.
Be a friend to yourself. Reach out, and in 3-D too.
Keep posting, pour it out. We'll listen.
