It kinda sounds like you are putting his needs and your own need to be needed by him ahead of your own well-being here. Bloomin' winter expanded on that to speak about co-dependency, and that is what I see as well here.
I'm not going to speculate about whether or not he is being abusive, but his behaviour screams of control issues. If he needs to control everything you do, then it is a sign that he feels so out of control within himself, and that is the only way he can derive some semblance of feeling in control again. It is very hard to live with. People like this are a giant pain in the Ass! I've lived with people like this before, and it was not fun.
I hear that you don't think he is being abusive, and frankly, asking a group of people who have been abused severely in their lives is going to get you comments pertaining to abuse being present, because abused people tend to see abuse everywhere, because their perceptions have been so skewed...due to abuse.
Having said that, I also know that constantly picking on every little thing you do wrong, or not to his standards in a relationship can really wear down your own confidence.
So, I guess the questions you may want to ask yourself are:
Are you willing to put your own sense of self-esteem and confidence second to his need for support with his issues? Is that what your idea of a "good little wife" is?
Aren't you just as important as he is? Is he going to support you once your confidence has eroded to nothing? Will you be able to support yourself and him once that happens, and it will if this keeps up...it's only a matter of time.
He can be the nicest guy in the world and still be eroding your confidence in yourself subtly, even if it is unintentionally.
