First of all I'm quite introverted. I'm part of a volunteer group where I befriended a few people especially 2 women in particular. I have often met one on one with woman A and woman B and I really value our friendships. Lately woman B asked if we could all meet as a 3 for a change and I said sure (although I was apprehensive about how it would change the dynamic). We all had a nice time and will meet again as a group. I do feel it probably spells the end of my 1 on 1s with each of them though. Is that silly?!
However another person that left the group long ago, woman C (who I also meet one on one for coffee sometimes) saw us together in the passing and asked if the 4 of us can all meet together soon and you know what? I don't want to.
I prefer to meet up with people one on one and I don't want it to become a big group thing. I've accepted that it is going to be 3 of us meeting from now on as it is but I really don't want to add this 4th person to the mix - who is a nice person but very quiet and doesn't fit with the dynamic imo. I love meeting her one on one. How would you respond to that?
