My wife didn't take anything except her clothes and toiletries for a long time. The first personal thing she took was a kewpie doll she'd had since she was a little girl. I hope she was working through some of her issues from her early childhood at that time.
I took D32 and our grandkids to NYC for a couple of days after Christmas. When we got home we found my wife had taken most of her stuff from the house. GD14 was so upset she called my wife and told her she wished she had a different grandma. The next day was New Years Eve. I was chatting on FB with my wife about some things GD14 said grandma had taken that belonged to her when there was a knock on the door and I was served with divorce papers.
My wife has a display case that's about 18 inches deep, 30 inches wide, and 40 inches deep that was completely filled with pretty glass, crystal, and ceramic pieces that I had given her over the years for anniversaries, Christmas, birthdays, and Valentines days presents. Very sentimental stuff like glass roses and lovebirds kissing. I couldn't believe it when she took that. GD14 asked her once what she did with it, whether she sat around and looked at it and she told her yes, that was what she did, she sat around and looked at it. Very strange.
I thought when she left all of her stuff there for so long that it was there because she didn't feel like she could be that person anymore. I thought that when she was ready for that stuff that she would be back to being comfortable with being that person again and that she would want to come back home then. Apparently I was wrong.
