Bobby,
Sorry I am not a woman but Hey.... I can relate a little with you.
W and I had been basically separated for almost three years. Yes we did live in the same house but separate rooms. All I can say is it "takes as long as it takes". About three weeks ago my wife moved back into OUR room but with the understanding she was NOT ready for sex. THEN two weeks ago I guess the moon and the stars aligned just right and we did ML. I know my wife is going through /went through menopause and an also think a MLC. It is taking her a while to get where we are today.
Maybe your W is waiting for you to make the first move? I know what you mean by "wanting her to participate" and not just be a “object” when you ML. That was the great part about my moving back to our room on her own. I May have been able to demand she did but like you said. I wanted her to because she wanted to.
Maybe you need to take her on a “date”...and doing so keep the frame of mind that this is a date you want to “take home”.. Wine and dancing (close dancing) does loosen up a woman….


And if I claim to be a wise man, well
It surely means that I don't know
