Long time lurker, first time poster, please be kind.
Me and DH are very close friends of 30 plus years with another couple. We've had a lot of interaction in each others lives and consider them our best mates.
Long story short it was their younger DS's 21st birthday yesterday. They had a party and didn't invite us.
It was mostly for friends of their DS which I totally get but they had a group of their own friends there (all age 50 plus like us) and I can't get my head round why we didn't get asked.
We had a party for DDs 18th a few months ago and invited them and it's my 50th in a few weeks and they're coming to that...DH is going out with male half of couple tonight so no rift.
I just feel a bit sad and left out about it.
