I may have issues with my family and I'm currently separated, but if I had a million dollars, I would give most of it to my and his family. I love them and if I can make their life easier with money, then there wouldn't be any second thoughts.
I would save some of the money and donate it to the arts. Not sure what "arts" so I would have to do some research first.
A bit greedy, I would also ask my family to send me on a trip across Europe and Asia as a nice big christmas present. I'm sorry, I can't pass up the opportunity!
