I keep catching my friends hanging out without me. Should I stop talking to them?

For the past several months, I’ve had a complicated relationship with my now somewhat-old group of friends. Towards the end of the school year last year, I kept seeing pictures and videos of them on social media hanging out without me, so I chose to stop talking to them. Over the summer, I found myself upset because I didn’t have a lot of friends after breaking off of the group so one night while I was at a party I sat down and started talking to them. I became friends with them again and things seemed to have gone back to normal just in time for the new school year. Then I started seeing pictures and videos of them on social media hanging out without me, this time with some freshman at my school who they just started talking to. I also found out that they have a group chat with a bunch of other people, but one of those people isn’t me. I want to stop hanging out with them again, but I don’t know many people who will get my social life going again. Plus, my friends are a fairly popular group, and this the first time I’ve really ever been able to see myself as popular and “in it”. I find my friends to be shitty, but I’ve also cut them from my social life before and it didn’t go well. What should I do?
