Christmas, a season for giving, loving ............ and splitting up?

It never accured to me before that such a happy time could also be relationship homocide. Though a few people have mentioned that they are going through a very rough patch, to the point of calling in the lawyers, right in the run up to Christmas.
 But why do we do this to ourselves? If Christmas, and weddings for that matter, threaten to tear us appart from our loved ones, why do we insist on indulging them? Why spend £1,000 on presents if the real cost of it all is spending Christmas with the prospect of a lonely New Year?
 Perhaps, though, it is unfair to blame the festive season. Perhaps it is infact our own insecurities infused with the inevitable alcohol content and massive debt that causes us to spiral into trouble.
 But either way, could you really give up Christmas to save everything else?
