"he treats her so well with kindness, respect, attentiveness, meets her emotional needs, etc.. and why would she give this up".
In my opinion, you need to really look into your listening skills. You will have periodic conversations with your W for forever, regardless of what happens in the next few weeks. You have a child together so there will be conferences and ball games and music concerts and summer care and so on. During any of these discussions, you need to be the above things: kind, respectful, attentive...
I dont think now is the time to meet her emotional needs. Now is the time to practice these skills. How can you be more attentive to your son? your family? your coworkers? How can you exhibit kindness?
