There are certain things that people deserve. Everyone deserves to be loved. Everyone deserves to be treated with a certain amount of respect. Everyone deserves a certain amount of benefit of the doubt. Everyone deserves to be happy.
These things apply until the person does something to give up their right to those things. Everyone deserves respect, except people who have shown you that they’re not worthy of it. Everyone deserves the benefit of the doubt until they prove that they can’t be trusted.
That applies to you, too. If someone isn’t treating you with respect, and you haven’t done anything to lose their respect, that’s unreasonable. Don’t try to take that burden on yourself.
