Arsene, how many posts! First, what an awesome b-day surprise! Second, I agree with giving your W more space.
This is what my coach would say: she's giving you a message (whether that makes sense or not) and the message is: "I'm done. Find someone else. Don't you get it? What do I have to do for you to get it?" Could she change the way she feels? Of course. But for now, you must convey that you get it. She knows you love her, she knows you want to save your M. Now, she needs to know she's free to leave if she wants to. If she feels this, she'll also be free to come back to the M. Anyway, that's what my coach told me and it makes sense in these sitchs. The WAS is like a kid trying to establish her independence. Look at your W from this perspective.
