You should stop caring if someone doesn’t care about you. It’ll make your life easier. If they only care about themself, that’s good for them. Whatever gets them by. You shouldn’t care if someone doesn’t care about you and only cares themself though. There’s only a handful of people, if that, that the majority of people in the world can count on. It’s what you make it. That’s truth for everyone. So, if a person only cares about themself, at least they have themselves in their corner, for sure. That’s a good thing.
