Yes. Generally, MWD advises "no R (relationship) talks!" at this stage. I see you not only continuing to have them, but even INITIATING them, and that's a DB'ing no-no.
Also, your husband not wanting to talk about what he likes in his affair partner is actually a form of RESPECT and LOVE, for you, and I'm glad at least ONE of you is being wise about that. You simply don't need to hear that -- it's not healthy.
