Do you think I should ask this friend about why she and the rest of the friends are excluding us from the gatherings?

or ask if they are mad at other friends inthe group as well? Or better not ask and it is a lost cause, cause they do not worth asking if they are not interested anymore why they change with us? And how to ask?

I am still part of a group friends and we all former classmates from high school. We graduated many many years ago, but for the last 6 years this particular group (of 7 women) got closer after a high school reunion 6 years ago. We were close beacuse after this reunion, we created a Whatasp friends group just for us, to chit chat, orgainze social gatherings, etc. We were doing ok cause in several occasions we did hang out together to have drinks either at restaurants or at the house of one of them, so lets say I thought we were lets say close. Everything was ok until the pandemic started and even after the pandemic got back to normalcy for some of those ladies but not all. When teh pandemic started inmy city 2 years ago, of course we could not hang out anymore but in few occasions, we gather by video call and chit chat from there. During those video conversations we promised that after the crisis improve we had to see in person again like old times. When the crisis was better, I (cause I was the only friend in the group who always had the initiative to suggest the group to go arrange a gathering, noone else did that to make the first step), I always suggested it was time to see eahc other again , all of the friends said "Sure", "we have to arrange something"

The time passed and nothing was done, even if me several times suggested the idea to hang out again and their response the same "Sure" "you decide and let me know". After that I stopped texting and suggesting anything.

sister we all know as well cause she also was a former classmate but she was not part of the Whatassp group though, only the sister). In the photo there was 4 of these friends, having a good time at the bday, with other friends too. But I overheard the invitation was for 5 friends of the group, only that one could not assist. And the rest of the friends group (3 remaining, including me) never were invited or even took into account. WTH!!!

After that celebration in May 3, some of those friends

through social media photos I found out they keep seeing each other on their own in different get togethers but they dont invite the rest of the group. I dont know what happened, if they got angry or mad at someone in the group months ago cause it is something Im not aware or know. Yesterday the same friends who keep hanging out posted a photo at the brithday of another one of those friends.

Should I ask why their odd behavior toward the rest of the group friends,?
