A woman might not be "feeling it," but is willing to put the work in because she knows it's the right thing to do and that the relationship is worth saving.
That woman is bored and unfufilled and will be looking for a lifeboat. Eventually the thoughts of the right thing do are - "I need to save myself, life is too short."
Women lead with their feelings, so if she wants to be with you she will do whatever it takes to make it work. Her feelings will be backed up by her actions. The key is to keep her attracted.
This is why men will live in a so-so marriage. "it's manageable, how much work would a D and new R take?" A man can make a decision like that and be OK. Women need their feelings stoked more to keep it hot.
If you read in the "piecing" forum you find lots of couples who don't understand this and they are still in "so-so" marriages where neither spoude is happy. Learn to read the real message.
husband - "When you say no, do you really mean yes?"
