I am sorry. It’s really unkind of him to ghost you like this. It shows you what kind of person he is.
But I’d say if he told you he broke up with you a year ago, he maybe doesn’t consider you two a couple. It sounds that you two were not on the same page and had a bit different vision of all this. I’d ship him a ring (if he didn’t take it when he broke up with you), hopefully you have his address and be done. I’d not expect his help with anything.
You spent so many years waiting for him. Waiting for his visits or for his divorce. Time to enjoy your life not waiting for anyone.
