I know she can change her mind however this is a firm action. It only a few weeks back that she was venting about hating that place and telling me she is looking for another place where she can set up long term and take D with her to live and it was not worth setting anything up whrere she is. this is a solid step back from that situation where she has both said and showing by actions that she is not prepared to make that step yet. It may well still come and it wont be the end of the world.
There is lots to get through yet but its good to see that run away train stop for a while.
