Arsene, you're doing great. It's amazing how many people are supporting you and care about you! It took me a while to catch up on your sitch.
Your daughter is a smart and sweet little girl. She's a blessing. And now you two can deepen your connection. That's the fortune in this misfortune.
Sorry about you feeling sad on your b-day. I'd feel the same way. You thought your W would be with you for the rest of your lives, and now she's behaving the way she's behaving.
My 2-cents: I think a shift is happening in her soul. Don't know if the shift will be strong enough to make her stop the A and "come to her senses," but there is definitely a shift.
I agree with everyone that you do need to take the focus away from her, at least to some extent. I know it's not easy. I know. But you must do this to preserve your sanity.
