When people show you who they are, believe them, said Oprah.

Do not confuse their one-time goodness with their nature of not giving a damn to you.
Do not confuse their one-time kindness with their all-time rudeness.
Do not confuse their one-time attention with their lack of attention all the time.

Protecting yourself is super power.

With that, it is also important to know that their reality does not affect your mindset.

Know their truth, distance yourself from them, yet at the same time, never think bad about them.

See them for who they could be while keeping yourself away from who they are!
