Well IMHO, I think you have hurt her in a way she might move forward find the healing method,something as being advertised as the deal of a lifetme. I've seen similar posts to the ones your XW is currently writing. This is my only my opinion, so take it for what you thik it is worth.
Yes, you have caused her very deep. I'm talking about the kind she doen't get over. she may turn to other substances to get her though those painful days, but they don't work well for her She felt she was give as much that could when something else happened. She is not in love with this OM. Her main objective is hurt you as badly as you've hurt her. In the meantime, she going to play kissy-kiss with the OM. She is using him, and apparently it must be work. She uses him to smear in your face every chance she gets, and uses him for the glorification . If he dumps her, she go find OM 2. Unfortunately, there are women who want help with these other men, who can gave them a great show. Your W tries to thrown this in your fame. Every time an ad comes in her paper about job, she wants you know it. So, she'll drop pictures of herself to post social media. She'll find ways to praise OM, and bread crumbs for you, just to keep you attached.
This is could go on for years......or until you and your W get expert therapist who knows how to heel couple coming back from an A. I would suggest you call one of couches at MWD. I think you have hurt her very deeply, and at the moment she was the hurt...........she turns to OM, to get rid of the bad stuff and she saw him at free ticket. Therefore, since an ow seem so good for you...........Your W thinks, why shouldn't have her turn?
Even if you just called MWD office to get them to help you know how to handle this situation I agree with what your W said about feeling very confused. Although is sounds confused, I think she's still in love with you. But convincing her, is another matter.
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!
