Welcome aboard. I hope you'll post often b/c it will speed up getting off moderation and others will respond to you more.
First let me tell you that an EA is serious and the fact that OM lives across country doesn't lessen the affects on your W. An EA is extremely addictive! Every time she gets ant type of contact from OM, it [censored] her right back in. That's why she is not succeeding in finding feelings for you. The OM excited her. Made her feel alive, attractive, etc. there is information on the web about PEA's. If I had not received the information in how the brain chemistry works in EA's, I would have destroyed my life......being under the influence of an EA.
Nothing short of your W getting the information (willingly) and cutting all ties with OM, will work.
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!
