:) Been there.
You get used to it.
And one day... when you finally get back together again with their side, it almost feels unnatural. You count the seconds until you're home again.
Well... last year, my dad died. And fate brought us back together again with moms side of the family. As much resentment I had towards them... I saw more clearly than ever.
Moms side was the only side where majority of the family showed up at his funeral. :) Not only did they show up, they did all of the leg work in preparing and seeing it thru. :'(
Needless to say, I've cut off all of my million and 1 relatives except for moms side. :)
Now? It's just a matter of getting re-acquainted. We have our ups and downs. But... after decades of fighting with moms side, it feels like the family is as complete as it was before we split. :o)
Moral of the long story: You'll find yourself back together again with your moms side. Especially, for funerals.
So... make the best of your time and experience WITHOUT moms side of the family, until that time. Your skills/experience in spending time in survival mode, comes in handy.
Good luck, my dear. I actually DID enjoy the experience of those Christmases in survival mode. I'm sure they'll toughen you up too.
