It's a long story (yes I shared it here at the time).
DH and I had a really nice friendship group with 4 other couples, we shared holidays and days/evenings out as well as a significant hobby.
Then DH died and (I felt) the group behaved very badly. I was basically dropped within a couple if days of his death, they let me down over the funeral arrangements and offers of help, and in the years that followed bitched and gossiped about my attempts to move on a build a new life.
We still have some shared aquaintances and are sometimes at the same events because of the hobby. I've made new friends and life is good.
One of the new friends, someone who was losely involved with the group back then, so knows what happened, and at the time, shared my outrage, has, through the hobby, been spending a lot of time with the three women from the old group. This is hurting me a lot. But I'm not a child and she's entitled to see who she wants.
As far as I and the group are concerned, we'll say a polite hello when we meet, but no one would ever know we used to be so close, and I can't find it in me to show any interest in them at all. They would probably have me along with the four of them if I wanted to go, but I don't.
Help me not to let this ruin my new friendship...?
