Losing childhood “friends”

I had a group of girlfriends that I was very close to in my late teens and early 20s. There were a lot of issues in that friendship group, but they were my core group. In my mid-20s our friendship fell apart when I had broken up with my boyfriend at the time. I felt like I wasn’t getting the support for making the right decision for myself, there was a lot of questioning of my decision. This coupled with feeling like the last friend in the group that would always be considered for any decision-making. These things drove a gap in our friendship and there was a little bit of tension however, nothing major broke out. Until one of the girls events came and she ended up inviting my ex-boyfriend and left me out. What hurt the most was the other girls didn’t say anything about it and I drifted apart from all of them. I still see pictures of them hanging out. I’m in my mid 30s and this is something I still think about. One of the girls, not the one that invited my ex, but another girl and I have started to rekindle in the last year… But the statement that was made was “our friendship drifted apart “. I do feel like we have a bond and it’s been years so there’s a possibility of growth… I will be having a conversation about what had happened the next time we meet. All this to say I can’t help but be sad that I will never have my “childhood friends. ”
It’s a loss and I’m not sure how to get over it. Yes I’ll be hopefully making new and other kinds of friendships, but I’ll never get the chance to have that “childhood group of friends”
