You have some very nice positives going right now. I wouldn't underestimate the significance of her letting her son go with you to Chicago. I like UDs focus on the melded family issue. I also wonder if the kids are the key to this sitch (her hesitation). I hope you have/had a great time in Chicago, not feeling too much pressure regarding her son, but being yourself. Hopefully, the kid will give you a chance and see the great father-figure you are, and over time, that W will see this as well.
