not enought time and too much distance

[any chance?]

Question:
Is it normal for my now XW to cut off all communication following the signing of the papers? She has now isolated herself from everyone, except the new boyfriend. Is this how the XW copes?

And, in a bizarre twist, she contacted my sister a few days ago, and made plans to meet with her in a couple of weeks. XW will not talk to me, but wants to meet up with my sister.

I must admit to not understanding any of this. I think I need to teach myself to cut her out of my life the way she has cut me out of hers. Just seems to be a hard thing to do. I am divorced (separated) now. Should probably start acting like it.
