Perhaps you need to be very specific in your demands and in stating the consequences of your demands not being met. You might have to go so far as to say "I want to have sex on Wednesday, Friday and Sunday. Your decision to meet or not meet my needs/wants in this regard will give me a clear signal about how much you care about this relationship. I am unwilling to stay in a passion-free marriage. Ask yourself "Is not having passionate sex with my wife more important than saving my marriage?". You are the only one who can answer this question. I eagerly await your decision.
"Tell me, what is it you plan to do with your one wild and precious life?" - Mary Oliver
