I have found over the years that if I'm not the one initiating a conversation or organizing a get together of some sort, then nothing happens. I've always been the one to put in the effort to maintain relationships, and I don't think it takes much effort and I also don't obsessively message people. So I just don't get why other people don't put in effort. I'm not asking that they message me all the time or invite me to gatherings all the time, but even occasionally would be nice, just so it appears like they have some interest in me. I know that if they're not putting in any effort then they're probably not worth having as friends or acquaintances, but when it's all you have, it's a big deal to burn that bridge, which I have done plenty times, leading to where I am now, with barely anyone in my life. Where I've been used, abused, mistreated, etc, I cut the link without regret, but where the relationship has hints of behaviour that I struggle with myself to tolerate, I accept it, a little painfully at times. just to have that relationship. I know people have busy lives, I get it, but when you see them putting in effort elsewhere and never toward you, it hurts.
