wuzLovesDubs, my dear friend,
If it were me, and my soon-to-be ex-hubby wanted me to admit that *I* committed adultery while he'd been out tomcatting around and lining up Mrs. #2, my answer to him would be "no, NO, and HELL-NO!".
I would *never* give him that satisfaction. Let him do the deed and take the consequences. He wants to have his cake and eat it too. That's not how things work in JW-land.
I'm laughing my butt off that it took a talking-to by the Elders™ to get it through his thick skull that his behaviour is totally inappropriate. Well, duh! Just shows how seriously he takes his belief system, because if he took it seriously he would have known that before he started scoping for a new lady friend.
I'm sorry that you have been married to a d!¢khead. We still love you though.
