From your wife's point of view, you were sending mixed signals. As we all know..that's disorienting and confusing and feels like limbo. I bet she doesn't like feeling that way, anymore than the rest of us!
From what I read, your talk really clarified things for both of you and helped her feel more secure.
But I think the others are right too...you now have some guidelines about when and how much of an OR talk to have.
