Before the mind developed certain degrees of basic correct understanding towards the modification of the mind, non-attachment, and mental and emotional independence, then the mind needs to move away from what it thinks and believes is disturbing or hurting itself, to have a few precious moments of limited and conditional peace and calmness, even if what the mind thinks and understands might not be true or completely true.
After the mind developed certain degrees of basic correct understanding towards the modification of the mind, non-attachment, and mental and emotional independence, then the mind understands that whatever it perceives or experiences cannot disturb or hurt itself unless it gives such 'power' or 'meaning' to such perceptions or experiences, and allows itself to be disturbed or hurt by them, even if it is something very ignorant, unpleasant or disagreeable, where any disturbance or hurt arise in the mind is due to its own incorrect understanding and reaction towards whatever it perceives or experiences that it doesn't like, doesn't agree with, and doesn't desire.
Meanwhile, the mind doesn't need to be continuously or repeatedly dealing with such ignorant, unpleasant or disagreeable affairs, interactions, ties and relationships, conditions or situations, where it can choose to move away from someone or something that it perceives as ignorant, unpleasant or disagreeable, if it's possible, not because the mind is being disturbed or hurt by that, but for the sake of conserving energy or not to be wasting energy onto dealing with such affairs, interactions, ties and relationships, conditions or situations that are ignorant, unpleasant or disagreeable, even if it's something related to one's immediate family members, such as one's spouse, partner, parents, siblings, relatives or friends, and without any dissatisfaction, disappointment, hurt, anger, hatred or resentment towards anyone or anything.
There is also nothing wrong if oneself feels very disturbed or hurt by someone or something, to the point that it's affecting one's physical and mental well-being, which also affects one's relationships with some others, and hence, it chooses to move away from someone or something that it thinks and believes is disturbing or hurting itself, that it feels disappointed, disturbed and hurt by, that it feels dissatisfied, angry, hating and resent towards, even if it's not all true, such as certain people blame all and everything else but themselves for all their physical and/or mental discomforts, shortcomings, imperfections, failures, mistakes, unhappiness, and unpleasant, disagreeable or undesirable experiences. At least, they can have a few precious moments of peace and calmness to be looking into their own mind to know and understand what is really going on in themselves, if they want.
It's the freedom of all minds for what they understand or don't understand, for how they feel or don't feel, for what they do or don't do with their life existence, or for what they desire or don't desire for themselves.
It's not selfish to move away from those who are ignorant and blaming all and everything else for all its unhappiness while inflict ignorant hurtful behavior unto oneself and others out of ignorance and unhappiness, even if they are one's family members or friends, in order not to be empowering such ignorance.
It's not a weakness to move away from someone or something that the mind perceives as something ignorant, unpleasant or disagreeable, even when all kinds of names and forms are just what they are. Or else, the mind cannot have the precious moments of calmness to see things as they are, if the mind is in a continuous state of disturbance or restlessness.
Inquire the truth of everything.
