Do you have any advice on ways to encourage my spouse? I believe her writing is excellent but she lacks confidence.

That's a difficult question, because I don't know your spouse or her writing. In general, from what I've observed, women tend to be somewhat more cautious. This means some good writing doesn't get published. The only thing I can suggest is to take a good section of her work and compare it to an equivalent short section of a published author's work, side-by-side, so to speak. If it's good enough to be published someone else shouldn't be able to tell which is published and which is not.
And, in fact, that's pretty much what editors do, if mentally.
