I am so happy that you returned and provided an update. Congratulations on selling your home and moving into a new one. New memories to be made and they will be happy ones. Glad everyone has settled in and the adjustment period is going along nicely.
As for your xw, she has realized for quite some time that she messed up and appears to be a bit jealous of what you have accomplished since she left. I think she was look for pity and maybe an offer of funding to help w/the place that they are living in. She is still out there in space. It's okay for her to admit she's not doing as well as she should be, but she sure doesn't want you to say anything to her about it.
I agree, it wouldn't have mattered which IC you went to, she was going to leave.
Continue moving forward and live your life to the fullest.
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.
