How would you feel if your husband were constantly disappointed in you? Constantly wanting you to be like the women in movies, or like his mother? How would you feel if even when you tried to make changes accordingly, he didn't even notice? If your every effort was not good enough? How would you feel?
Think of it from his point of view. You've been married a while, and you have not previously given him any indication that you want him to take you in hand. He, being a decent man, has thus not done so. But now you are saying that you want a relationship. He may be interested, or he may feel cautious, or he may wonder if you really want it, or he may not be sure exactly what you want, or whether or not it is for him. He loves you and he is prepared to give it a try, but he needs to think about it and find his own way to take you in hand, he does not want to be dictated to by you. He also (very wisely, in fact) wants to take it slowly, and he doesn't necessarily want to talk to you explicitly about it. Creating a relationship is an evolutionary process, not a recipe he must follow. Were he to follow your recipe, you would not be satisfied, because you would be in control!
