Invited friend and her kids out for the day. Arrived to find friend had invited two other of her close friends and their children. I felt a bit awkward and left out as they are obviously close friends and didn't make much effort to speak to me. I really tried, but when they kept returning to talk about shared memories etc it was quite difficult.
They then added a collection of pictures on Facebook afterwards with no mention that my children and I were even there. Friend then commented what wonderful friends she has, tagging the two she invited.
It was me who originally invited! Friend I invited has always been lovely and refers to be as one of her best mates usually. Not sure what to make of all this but feel quite cross and hurt. Aibu to feel this way and what's the best approach to deal with it? Become more distant? Say something (how without seeming like a six year old?!) Forget it?
