Why are you waiting for her to initiate things? Why don't you?As a person who loves Christmas I do enjoy all the decorating, family time, great food, and gift exchanging; but as far as my home life it's quite depressing between my wife and I and 2013 does not look too promising for us. So more than likely this will be our last Christmas together because she's not even trying to fix things or is showing any interest.
Perhaps she thinks exactly the same way as you do. That you are not putting any effort either.
