Not necessarily. Plus, it may never happen or take too long. A simpler, faster way to try to return her passion is to become an objet du desir of another female (haunted_by_my_past, you do not have to consummate - you just have to become an object du desir and let the wife know about it or have her figure it out or guess or whatever - you get the point).

It is much simpler, is a tried and true way to revive spousal interest, and should work since we already know from haunted_by_my_past that the wife gets paranoid when haunted_by_my_past steps out to make phone calls. So despite all her coldness, she still cares enough (even if it is due to simple possessiveness and not to her having any remnant passion for haunted_by_my_past) to get paranoid. If she were completely indifferent, she would not get paranoid. So capitalize on it - insert a fun dynamic into the relationship.

Just be careful enough with the female who will make you her objet du desir - she is a human, too, and has feelings of her own that should be respected.

This method of reviving spousal passion predates the modern methods, such as:

- paid counseling
- endless communication, communication, communication
- working on issues
- filling worksheets listing what initially attracted you to each other
- attending weekend retreats to improve the relationship
- reaffirming the vows via expensive ceremonies
- ...

by many centuries , and as such may be dubbed a "folk remedy".

haunted_by_my_past, but you already knew it - you picked up on her paranoia many posts ago, so I am just adding detail to what you already know on your own.
