Brian: I like the idea of writing a letter to get my thoughts together. I'm a little afraid that I may hear nothing from them...ever! My girlfriend suggested reading the letter to them. I think I may do that. My girlfriend does want to spend Christmas with me. I’ve already taken her on family vacation and to their house for my birthday. I feel like it's evident at this point (I don't bring anyone to my parents). That is why I was thinking about doing it over Christmas. I feel like it will be the elephant in the room. But I think all of you are right about it causing a lot more stress!!
Keltic63: I love the idea of letting them know what I expect! That's just great psychology and social awareness skills! I teach this precise skill where I work and yet it never crossed my mind!

Thanks man!
Kevin: You are so right about twisting words! My mother is the queen of this! Great point!
Thank you guys so much! I feel much more prepared! Any ideas about wording or how to bring it up are still welcome! I'm scared to death!!
