One thing you could do (and I don't remember where I read this) is that you can suggest to your spouse that going to this would help you. Say something along the lines of "i'm having trouble communicating and I think this would help me communicate better. Would you be willing to help me do so?" That way this is about you learning something new and she assisting you in doing so.
I believe I may have gotten that suggestion from the Retrovaille website, but can't be sure.
