When was the last time someone genuinely apologized to you about something they did to you?
Most people are so focused on themselves they dont care in the slightest if they hurt you.
You could explain why they've wronged you until you are too tired to speak and they will act as if you are the one at fault. The desire to apologize to someone requires having felt remorse for your actions, if theres no remorse, youre not going to get it from them.
Its mental illness to expect people to feel bad for wronging you, so its mental illness to feel remorse for wronging others, Why do you care about hurting others feelings when they never think about you or care? Is it not mental illness to continue to expect you to be treated with empathy when it consistently doesn't happen?

If you think about how your actions effect other people you are an outlier and expecting reciprocity is delusional because no one is going to give it
