Friends - when to call it quits

I’m struggling with whether or not I should keep putting effort into maintaining my high school friendships or not. We were all very close through high school (5 of us) and one of my friends is from middle school. We’re all 33/34 years old now.

Ever since I got pregnant and then had my daughter 2 years ago, I feel like I’ve become so distant from them. Nobody seemed that excited when I announced my pregnancy and I barely heard from them at all for 9 months. They all met my daughter when she was 3 months old but they honestly haven’t been part of her life since. To be fair, we didn’t see each other super frequently prior to me getting pregnant...maybe 4-5 group get-togethers a year. Every time I hung out with them though, I felt so disconnected. I wasn’t interested in the topics they discussed and although I asked questions and got involved in convo, nobody ever asked how I was doing or showed much interest in my life. I had a BIG talk with my “best friend” early this year because we both felt like the friendship had fizzled. She basically told me she needs more out of her friendships and can’t just see someone once a year and expect to be close. I don’t feel that way...if people’s lives are busy, I am happy if I get to see friends once a year! However, this friend of mine apparently needs more. She also said I need to open up more and share more details about the super personal parts of my life. I told her I’ve never been that type and it takes me a while to get to the personal details, and if nobody ever shows interest in my life, I’m not going to feel “ready” to share those things.

Anyways, they are all trying to get together this Saturday. If I’m feeling disconnected and like I really don’t care to catch up, I probably shouldn’t go right? How do you gracefully leave a group of friends? I feel weird about it since they are my childhood friends but I’m so busy with my family life and don’t like prioritizing people who don’t add anything positive to my life. I think part of it is also that our lives have taken totally different paths and everyone else is still unmarried and without kids. Sometimes I feel like we can’t relate well anymore.

Any opinions?
