I know exactly how you feel. I have two teens at home. Mt DD visits her boyfriend Xmas morning and has lunch at home (she's def not a mammas girl, hates to be hugged etc). My youngest is only 14 so he's stuck here! No 2 child is coming home from Uni, v excited I am and still think of him as my baby, the boys put up with it cos I am such a family/Xmas freak.
I will not see No 1 son this year, too much water under the bridge and to me it is a bereavement, I feel like a failure and also my Dad has just died, so he won't actually be around, even tho he was in his care home for the last two years, we still went to see him.
I went stay with my BF parent's at Xmas when i was younger...only child...now I know how much it would have hurt my Mum and dad, even tho they wanted me to be happy.
I dread the day when it's just me and DH for Xmas...but maybe by then I might have grandchildre. But then we have the MIL and me tossup, who will they go to??
I just think that any time I spend with them is precious but I do think that you need to be more vocal. Tell them how you feel, maybe they think you're just laid back about stuff. Tell them you want to be a Mum and have them there, even if it's only for a quick drink and a mince pie. Do you get them presents, do they buy for you? When do you exchange gifts? I bet you spoil them all!!!
