It sounds like you might not know the people who bailed enough to invest that much emotionally into them.
If you thought you did and now you’re not sure then it sounds like you can now have some clarity that they might not be as close to you as you feel to them. Time to pause and question why you’re putting emotional energy into people who aren’t invested.
I’ve been working on this a lot myself. I kind of realized that I was investing a lot of time and energy into friends who live a 5 hour drive away and it’s really convenient for them to have me always drive there. On the flip side none of them have ever made the drive to come visit me. So instead of rearranging my whole life to make a weekend work with them and expending great energy and effort to do so, I started bowing out more often. It’s been better for my peace. Love my friends but I don’t have to run myself ragged visiting all the time because they certainly aren’t doing that.
I put together a huge birthday party for my sister including this whole group. My birthday came around? No one did anything for me and they were all busy, even my sister. That’s fine, it’s telling me I don’t need to make the effort in the future.
I don’t put in effort to the extent that it bothers me about it. If it’s convenient sure. If not oh well next time.
One of our friends used to get all bent out of shape because she would prepare all of this food for a party and no one would eat it. I was like girl, stop preparing food then if it’s making you upset. If people get hungry we’ll order pizza.
Sometimes the things you think people will be into are not the things people want to do.
Scale back. Neuroboring people don’t put as much effort into coworkers and social connections as much as I think ADHD brains do because I don’t think they think about it that hard. I learned this when I invited coworkers to my wedding and 2 showed up for like an hour - and I’m pretty sure one of them dragged the other.
People with kids are super flaky too.
I’m just saying yeah you aren’t the priority to these people. Find people who will make you the priority. Keep looking. These connections happen slowly and change over time.
