You talk a lot about "honest communication," and you seem to think that your wife saying "maybe" when she really thinks "no" is not honest communication.
Do I have that correct?
If so, I think you need to adjust your expectations.
It does sound like your wife would benefit from learning to express her thoughts and feelings more directly. But I think it is unrealistic to expect her to adopt a communication style that avoids the sort of social hedging that most women (most people?) use and understand.
Sometimes the way you talk about communications gives me the impression that the only communication you think is honest is communication that fits the Asperger's stereotype. If that's a true reflection of your attitude, then you need to change, not just your wife.
