"Thinking about asking him to pay me the funds that is owed (salary, loan), and once that is received, ask him how we can disolve the business. I cannot continue to work with him. It's too gruelling and it is delaying the end. I need to be away from him. "
That is pretty drastic. You do realize that you haven't changed. You're still making it all about you and you continue with your "all or nothing" attitude. You haven't gotten yourself strong yet which is why you're doing this.
"Is ending my business going against DB efforts?"
Not necessarily, but it's definitely not going to help. He already told you he felt overwhelmed and so you dumping the business onto him isn't going to help.
"or is this just me pushing away? (to save myself?)."
This isn't "saving yourself". It's conflict avoidance. You can't stop yourself from thinking about things which is why you want to leave. You've never gotten to that neutral place where you are detached emotionally. Your attitude now is - Well if he's not going to want me, I'm leaving.
Entirely up to you of course.
