Hey Mozza and Tarheel,
I am having similar experience with my WAH leaving stuff at my house and claiming he has stuff of mine. He seems to often use the stuff as an excuse to keep in contact.

Sorry but the stuff they are leaving behind gives no indication that they are holding on. It could be that they are too lazy or irritated to come get it. Maybe they forgot about it. I know I have left stuff at boyfriend's homes and now I wonder if they thought the same way you are. Let me tell you, there was no reason I left things there other than I just could not be bothered to go get it. Too much hassle dealing with them, didn't want to see/talk to them again, didn't care about the stuff that much. Figured I could get it "later" and then never did. Don't read into it unless she is obviously using the stuff as a way to keep you on the hook. (like coming by daily or contacting you regularly about the things)

Probably the WAWs are using you as an easy storage option. I say box the things up and put them away out of sight if possible. As more time passes you can let her know the things are in boxes, and eventually you can insist she or someone else picks it up.

Good luck Mozza!
Hugs, Lisa
