Not trying to add to your stress, but having an expectation of support from an active alcoholic is like going to the hardware store for bread.
I should know, I've wandered the aisles of Home Depot looking for muffins
Find some real friends to help you move. Or move it one lousy piece at a time if you have to. I did the Uhaul move with my best girlfriend, a few months later (after taking the asshat back), I made him come and get his stuff out of my house-with two local cops monitoring. Sigh.....
That's what my life came to.
I'm a little younger than you, not much.
Good luck!
