Those with healthy boundaries are firm but flexible.
They give support and accept it.
They respect their feelings, needs, opinions, and rights, and those of others, but are clear about their separateness.
They are responsible for their own happiness and allow others to be responsible for their happiness.
They are assertive and respectful of the rights of others to be assertive. They are able to negotiate and compromise, have empathy for others, are able to make mistakes without damaging their self-esteem, and have an internal sense of personal identity.
Those with healthy boundaries are comfortable with themselves, and make others comfortable around them. They live in houses with fences and gates that allow access only to those who respect their boundaries.
Learning to set healthy boundaries can feel uncomfortable, even scary, because it may go against the grain of the survival skills we learned in childhood - particularly if our caretakers were physically, sexually, or emotionally abusive.
Narcissists can also oscillate between loose and rigid boundaries. Both styles are known to the narcissist. When a person withdraws from a narcissist the response can often be to flip into a more co-narcissistic style of relatedness.
