Wow, a lot of great feedback on this thread.
Dubs seem to swing back and forth like a clock pendulum. From hot to cold and back again. From my own experience I know it's hard but if you can keep being patient she may very well swing back again and this time be more convinced that it's not the truth. Being a dub takes a lot of effort and unless she is 100% convinced it's the truth she will tire out. IMHO.
But, I just want you to know that I understand the feeling of loss and frustration that you have right now. It can eat you up and make you act very differently from your normal personality if you let it. Please keep posting here and venting here because there are a lot of great posters who will listen and reply.
