We are in our 40's and this is our first marriage.  I own my house so we have merged two households together and were giving items away last year when he moved in because of dupes and space issues.  
Because of this my fiance says we don't need anything and he doesn't want to register for anything, anywhere!  I suggested registering for our honeymoon and he didn't like that idea either.  I tried to explain to him that people don't know what we want and/or need but it's not sinking in.
Does anyone have any other suggestions?
