My W only took her clothes when she left. She has since come back for the airbed. I let her know that she can take what ever she needs anytime. I am trying to be supportive as possible to her and she appreciates it.
I wouldn't read anything into the fact that they take just the bare minimum of belongings..or that they come back and get more stuff over time.
