no you're not being selfish.... why not this year your husband does the cooking and cleaning? tell him if he'll commit to doing that then you're ok with it. not even talking about your paycut here ... but i don't think it's fair that all these years the responsibility has been on you to do christmas eve. or have a potluck! change it up this year :-) make it less work for you. tell him you're feeling down and to make it better he can do all the cleaning and let his family know it's a potluck dinner this year.
