I get this, not nice, similar happened to me when my kids were small, just when I really needed to have some sort of social life. Things had been sort of ok until the wife of a high profile person (won't give details) moved to the area and sent their child to our local school and there was a huge flurry of excitement as everyone wanted to be in a social set that revolved around her. My friend and I found ourselves more and more sidelined as other aquaintences started to drop the things we used to do and hang on to the edges of this new in-crowd instead. Some quite unpleasent things happened, for example they all signed up to a particular keep fit class so nobody else could get in and then they all stopped going on the same day so the person who ran it had no clients. It's only amusing looking back, it wasn't at the time. Anyway, not to be deterred, my friend and i advertised on the local social media group, think it was called Streetlife back then, and set up a monthly 'girls night out' at the local pub for local women who wanted to meet new local people - and it was really fun! This is always an option if you feel you are missing out. However, unfortunately for us, after a few months, the in-crowd heard we were having fun and started turning up en-mass. They ignored those of us who had been organising and attending the evenings out, complained loudly about the pub and started using the 'girls night out' handle to post up other 'more classy' venues and activities - which meant people had to travel further, get lifts, taxis etc and go to expensive places where you had to dress up. The whole point of being a friendly and inclusive, casual and within walking distance, way of meeting other local women disappeared and it fell apart. I guess it was still worth doing, as we got to know some new people and broadened our horizons. I think it's hard to find you are on the periphery and possibly missing out. Hope you can find or create something that makes you feel more included.
