Going to be honest, that story depressed the hell out of me. Going through boxes searching for the deed of my home. And I found my W poems written on how in love she was with me over the years. Not just lust, but real love and passion. I find this hard to just throw away when I have found messages right after the A on how she loves me. But simply wants to leave the MR.
Your story sounds as if she used her H until something better came along. And I find it hard to believe that she knew this guy was the one from the moment they shook hands. That sounds more like attraction and lust. Now things have worked out for them. But I honestly don't know know if I could be around someone like that who abandoned their family. And yiur good for doing that, especially with yiur currently going through.
But I am curious as to what this friend has to say about your current sitch? Because she has been in H shoes.
