Doc, I understand your fear, and live my own version of it. I don't think you're going to find indifference in your W. She's not sending those kind of nonverbals to you.
Is she sending hints of wanting to move forward with physical intimacy? Do you two have a good sexual history together? Is it a matter of "getting back on the horse?" Do you have a troubled sexual history, and must approach it differently?
