I dunno, sister. How bad to you want to marry this guy? Cuz here's a news flash for you: Christmas comes around ever 365 days. This is not a one time situation. You two will face this dilemma year after year. So a lot depends on how you work it out this year.
When DH & I were engaged we spent two Christmases apart, mostly because I was working(I'm a nurse) and we didn't live in the same town. So we delayed our little Christmas until a few days later. No problem. The first year married was a little harder. We lived 400 miles away from our families. I had to work. We ended up staying in Atlanta rather than going home, and I thought his parents were going to have heart attacks! No one in their family had EVER defied tradition. So of course, it was my fault. But they got over it(eventually.) We stayed home and started our own traditions. It felt weird that first year, and we missed seeing our extended families, but it was really important for us to be together.
We've been married 28+ years now. We stopped trying to go home for the holidays after DS turned 5--it was getting harder and harder for Santa to find us

We stayed home the next year and invited our families to come see us, for a change. Guess what? Apparently the road doesn't run both ways.

We started creating our own family traditions and now our kids don't want to travel at the holidays. They want to stay home and enjoy the way WE celebrate.
You know what was the most difficult part of creating traditions? blending our ideas of what we believed constituted a "real" holiday. My DH about fainted when I put collard greens on the Thanksgiving table.

He said that was poor people's food. We "needed" green peas. Well, I'm *going* to have my collards at holidays, because, well, they're holiday foods. Now we have both and everybody's happy.
think long and hard about how you want to do this. If you absolutley cannot stand to miss Christmas with your family, then maybe you ought to reconsider this relationship. Maybe you need to move back home and find a nice boy back in Minnesota. But you know, you'd have the same problem there--he'd want to go to his folks and you'd want to go to yours. Guess you better stick with the great guy you've got and work out something you can both live with.
