Just a rant really...
Some background: my DM died when I was 11 and my DF married my SM when I was 24 after having been with her for a while. I am my DF's only DC and my DC are his only DGC. My was also previously widowed and has three grown up DDs and five DGC. Since I didn't grow up with my SM I don't think of her as a SM, more as my DF's DW iykwim. I don't find SM an easy person to get on with, among many ishoos she has my DF completely under her thumb. But that being said, I totally accept that she comes first with him, he is happy with her and I'm glad he isn't on his own and lonely.
We (me, DH and our DC) live a good 2 hour drive from DF/SM and we see them around every couple of months. Usually this involves us visiting them. They are not keen on visiting us and much prefer us going up to be part of the crowd at one of SM's family gettogethers. SM's family mostly live very near by and DF/SM's lives revolve around spending time with them and being on hand to help out with school runs, babysitting, etc.
One of thee rare occasions that DF/SM usually come to visit us is on my DC's birthdays. Both my DC have birthdays close together in January and we always have a family party, inviting my ILs, DF, SM and her family. So I phone up yesterday to say which date we have arranged for the next birthday bash. I deliberately chose a date that was convenient for Dstepsis as I knew DF/SM would be annoyed if I didn't take her into consideration. It is the date of my DS's birthday and roughly the date we always have for the party. But SM said "Oh, I'm doing the refreshments at church that day, DF can come on his own with Dstepsis and family. At which DF starts stammering on about how he didn't want to come without SM and he and SM can always come another time. I know what will happen, he and SM will not "come another time", there will just be another invite for us to go to yet another SM family bash.
I'm so pissed off, why can't my DF make the effort once a year to come and see his DGC on their birthdays when he spends so much time with SM's DGC?
