Glad to hear that you are detaching - the lack of bad dreams is a sign that you are cleared the trauma of all of this.
I have been broken up with her for a little over three months and she has since recycled her ex. My gut says she re-engages (probably influenced by my readings on here) but my head says there is no way she does.
Sounds like she never fully let go of the ex. That's never a good thing.
I'd hope you to stay around and help with the newbies. Helping others is a great way to help ourselves.
