Marriage roles and expectations

I have been married for 19 years, and we've survived though all the struggles that marriages face. And then some.
Recently, my wife has been dealing with a lot of stress/anxiety issues resulting in sleep disorders. One issue that has some forth is that she has always felt uncomfortable with lack of role expectations and this has seeded a lot of resentment and bitterness. TO understand my dilemma some brief back ground. I am a first generation Christian and a product of a divorced family( lived with my mom). My wife grew up in a Christian home. She is a very detailed orientated person. I am more abstract orientated, but I can adapt to working with details to some degree. I am a shift worker. She works office hours.
WHile I see this a need for my wife to be able to function and realize that providing such clearer expectation would benefit our marriage. . we have taken some marriage enhancement type courses, but there primarily dealt with more spiritual and relational issues. Essentially she would like a "job description" of sorts, and I have no idea where to begin.

Any recommendations --books, online seminars etc. I know there has to be something out there.

Is there a pastor or a mature Christian couple that could sit down with you two and talk through expectations? The Bible does not present a detailed job description beyond the basic principles I am sure you are familiar with.

As a pastor I often work with couples seeking to resolve some of these issues.

One book I have found that has helped many couples is Gary Chapman's, The Five Love Languages. It is excellent at discovering how to relate to each other in ways that are received as expressions of love.
