Sam, It's a bumpy ride when you are dealing w/someone in crisis. I do think she's missing the "friendship" side of things w/you, but notice has she was bringing up the past and the tings from the past....it's part of trying to see where she was and where she is right now.
Sometimes, when they want to be friends and are being nice, you have to be on your guard because the other shoe is going to drop, i.e., the request for the boat over Memorial Day weekend. Good grief that's a bit away and anything can happen between now and then. Unless you are ready to say yes about that little venture, I would continue to table it for a while.
Friendship to mlcers is entirely different than it is to normal people. They all want to be friends after divorces and it's like they haven't got a clue as to what they've put us through the entire time. Friendship can occur, but it's going to take some time and foregiveness before it can happen.
Try to take things one day at a time. Your wife has a ways to go and don't be surprised if she wants to talk about the past again and then drop another request on you.
Sam, take are of yourself. Keep the focus on you and your furry friends.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
