Asking Eric: Am I justified in asking for these things back?

Dear Eric: During the process of our moving from a large house to an apartment in a retirement community, my daughter-in-law asked my son to leave their house. I had already arranged to give them many things, including my late daughter’s artwork, two antique Chinese wedding chests and a Turkish rug. I paid to have these things, as well as a dining set, two sofas, and beds, moved to their house, thinking that they would get back together.
