It is the least, or the most to wish for being rejected for your own mistakes. Not for what someone else has told about you. Things that are not true, biased, or otherwise invalid. You hope that people close to you form their own opinions and are open about it.
You can be completely unprepared for your assumptions, your understanding of a situation, of a relationship, not matching the reality of another person.
But there are no guarantees.
Anyway, do not assume.
