For me, detaching was about respecting my WAW's wishes to be away from me. I let her go. 2 months no contact. I even helped her move and told her I hope she found happiness.
I know how hard it is. I obsessed like crazy! There were days I didn't know if I could go on. Slowly the days added up and my WAW's heart softened.
What good can come from talking to your W about the toys? Take a step back and see it from an outsiders point of view. Do you have an agenda in regards to asking her? Hoping she will see the error of her ways and throw them away?
