Hello, I'll Make Tea,
Being rules orientated, opinionated and even having a bit of a controlling personality, IMHO, is not a symptom of PTSD.
Someone once explained to me that having PTSD can and does change a person, but it does not change the person's fundamental personality. In other words, it's like a blanket thrown over one's personality with the more moderate qualities subdued and the extremes fight to be expressed. Someone who is very critical is prone to be more critical of themselves and others; someone who is driven becomes very hyper-aroused easily and can turn explosive without a lot of prompting; someone who is fundamentally laid back becomes more easily, and chronically, depressed. That being said, most people want/need to feel they have some control over their lives - you wouldn't be writing if you didn't own some of that yourself, eh?
It's my belief that most of us have at least some rules. Often those rules clash when we're in close relationship to others. It's the stuff that causes common every day "fights" between couples. But couples find common ground, because they want the relationship to continue and evolve. What you're talking about is different. You're talking about (1) having mutual respect (or lack of it) between the parties, (2) addressing the practical side/s of your relationship, i.e. who takes out the trash and why, and (3) standards.
If I understand you correctly, the two of you have come to an agreement that he's the "bread winner" and you're the homemaker. I don't suppose you tell him how to do his job, do you? Why should he tell you how to keep house?
As Abstract pointed out, why is he making you responsible for his emotional state as reflected in how well the floor is cleaned? When it comes to how clean the floor is, toilet lid being left up, or what's the "right" way to fold towels - The only purpose in over focusing on those types of things is to cause unnecessary turmoil and strife that neither of you need,
IF the two of you want to continue a relationship.
His sleep problem is his to deal with regardless of how clean the house is. Those are two entirely separate things.
If
his opinion of how well you clean the floor isn't up to his standard, yet you're doing it to a relatively decent standard, then the problem is his - solely his. If he wants it cleaner, let him do it, and don't feel guilty about it. Your purpose in life isn't to live up to his standards of cleanliness. And, you feeling humiliated if he cleans the floor after you've already cleaned it is just the reverse of him feeling less than perfect if the floor isn't cleaned to his high standard.
It sounds to me like you're both taking what the other person does (or doesn't do) personally. Maybe.
Narcissistic personality is something I have recently been reading about...maybe some similarities here? Just throwing it out there...
Narcissistic Personality Disorder is a very real threat. If he is NPD it can really send you into a downward spiral, a deep one, very quickly, that is difficult to get out of (trust me). I'd suggest learning more about it. Of course, you can't diagnose him. But learning about it can give you some indication if NPD applies to him, or whether he simply has very high standards, is rather critical, and is highly organized. If it's latter, then the two of you may want to consider couple's counseling so that both of you learn what's reasonable to expect from each other in the relationship, and what's reasonable for you to accept and expect of yourself.
