Thank you all for your reassuring words! I think our moving will be a shock to D4, but I will for sure keep her surrounded by her "stuff" while at the same time allowing her to make lots of choices about her room and she will always be deeply loved by me. I grew up not just in a hometown, but also in one home all my life. I had hoped to provide that sense of permanence for her, but sadly it was not meant to be.
I know there will be many tears shed by D4 over this and I'm sure I'll do the same because of how it will affect her, but as with the D process...given time, patience and love she will come to enjoy the new living arrangement we both will build together for ourselves. These days this is truly the only sad aspect of my sitch that I still struggle with.
