Divorced Parents

Being from a "Broken" Family is never fun. Today I had to make up my mind as to who to spend my Christmas this year. My dad lives in Puerto Rico and he asked me to spend Christmas with him this year which i haven't done since I was like 8. He called me and said he was buying the plane tickets for my brother, his girlfriend, and my nephew along with the ones for my step brother. When he asked me I said no because I am used to spending it with my mom here at home but once I said no I could here a little bit of sadness when he said that it was ok and that he understood. About 2 hours after I felt kinda bad for turning down his offer and I agreed to go spend Christmas with him and when I told my mom I knew she was a bit sad right away and that hurt me as well. Its too late now to say no to my dad and but i'm kind off nervous as to how this Christmas might be and how home sick i'm going to get even though i'm only going for a week. Having divorced parents is a pain in the ass when i have to make these type of decisions.
