The first holiday season after a divorce or separation can place tremendous emotional strain on the best of us. Now that you and your ex have parted ways, the holiday parties and family gatherings you have been celebrating for years as a couple suddenly seem daunting and complicated. Who gets to go to which parties? How do you "share custody" of friendships? What do you say when someone asks why your better half is no longer at your side? It's enough to make an already emotionally fraught season barely tolerable.
