Sad, in a way...

My ex is asking me to return things to him that I gave back months ago. Is he that completely retarded that he can't remember getting them back? More and more over the past 6 months, I have realized that he really was not that smart. How sad is it that I am just realizing that now? Why couldn't I have realized it before I moved in with him, or before we got serious.... Who knew??? He's also claiming that my refusal to return the items (that he already has) is me being bitter and playing the victim, and that I'm going off the deep end. HUH????
