As Michelle said, it's great that she wants you to be involved in their lives and meet you halfway to help make an important event for you and your son happen. As with the negatives, though, I think it's best to acknowledge her gesture and let it go - since reading into either the positives or the negatives can trip one up very quickly. That's the wonderful thing about staying hopeful - once it's inside of you and you believe in it - it's with you through all even the darkest of moments - so you can have the same detachment no matter what happens.
I imagine that allowing yourself to feel what you're feeling - all that sadness - is a good way to let go of a lot of your own pain - and doing so also helps you stay calm and focused when you talk with your W - and deal with some of the matters that this kind of situation brings up.
