I have been in a friendship group with A & B for the best part of 30 years. We have been through all of life's milestones together - meeting partners, getting dumped, finding our DHs, hen parties, weddings, been each others bridesmaids, babies, godmothers etc etc. A & B knew each other before I knew them, but it's never been an issue, and I always respected that they had a friendship outside of our group. Likewise, I would do things separately with either one of them, depending on shared and common interests.
We all obviously have our own other friends outside of our friendship (we don't all live that near to each other any more) which is absolutely normal. However, in the last couple of years, B has integrated into a group of A's friends, and now it seems that they do everything together that we used to.
I'm so sad at seeing pictures of them all having weekends away together, nights out etc in exactly the way we used to. I don't get invited, and they don't make any effort to arrange anything with me. I just feel like I have been replaced in the friendship group by these other women.
To top it all, friend A had a 'big' birthday last year, and I wasn't invited. The realisation that I had not been included in one of our life milestones really upset me. I have spoken to her about it since, but she shrugged it off and said it was no big deal. She did apologise for upsetting me, but the friendship feels really one-sided, and she hasn't really made much effort since. I really think my friendship with A is over.
I'm on the fence with B, as I was included in her milestone birthday celebrations, and she is aware of how I feel about the A situation, but still continues to gush about this great new circle of friends (who are actually really A's friends that she has infiltrated).
I may not have explained this very well, and it probably sounds quite childish from someone who is old enough to know better. But the summary is that I feel that I have been ejected from our friendship group and replaced by a better offer.
Am I reasonable to feel like this? Should I fight for it? Or just let it go?
