New to site and really could use some help

I have been married a long time. My husband has ADHD, I do not. He wants to be in control of everything from money to household. A project will be started and then dropped and then a new one will begin. I do not know how much more I can take. He wants to do everything himself with no help but nothing gets done! We have three cars that do not run because he is going to fix them. Of course it's been over a year with them just sitting there. We have an old house that needs fixing up and all the rooms have been started but thats it. If I complain he gets angry because he feels I want things done asap. Forget about hiring someone because he will not have that. He wants to do it all. And don't get me started on the piles of papers, magazines etc... things he wants to go through before he can throw them out. But I have been around long enough to know that NOTHING gets thrown out! Am I alone with this or are there any others going through this too? Any help would be great...
