WW said she was just trying to find the right time to end things. My reply was that I don't want to know about the right time,I want to know when it's over, and repeated that she couldn't continue to use me as a dutiful husband while behaving like this.
Much better!
You have drawn a protective line around yourself, and told her you won't be "used". So now, don't worry about what to do to her. Just protect your own feelings, and when she tempt checks or any form of manipulation........you can either repeat how you will not be used as a dutiful H, or walk out of the room......or whatever you need to do to protect your feelings.
You said you needed to be energized and regain passion. When we feel beaten down by another person or situation, it suks the life force from our spirit, self-confidence, self-esteem, self-respect. IMHO, you need to focus on what is best for you. Be your own best friend, instead of trying to be the model, or dutiful H. Whether the M survives or not, YOU need to survive. And you will..........I believe this could be a turning point for you.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
