Did you wish your Ex-es (+ family) a Merry Christmas? Why?

This was my first Christmas in 3 years without my Ex, I did not message her on Christmas to wish her a Merry Christmas!

I do not feel wrong for not wishing her a Merry Christmas (I just feel a little weird, like there's something I forgot to do.), but I feel wrong for not wishing her family (specially her brother and sisters) a Merry Christmas, they had nothing to do with the break-up but for many reasons I prefer not to have any contact with them.

Anyways I was afraid it was going to be harder then this but it passed. I was wondering if you still wished you Ex-es Merry Christmas?
