What are the halachic obligations are to honor a mother or father that are a narcissist? An adult child may be trying to separate from emotional abuse and codependent relationship but this can often mean ignoring a parent(non-contact). Standing for a parent would reinforce unhealthy notions in the child.
I have looked at similar answers and am asking in regards to specifically narcissistic parents.
One of the sources I saw was In regards to Torah and Rabbinical writings, how does "honor your father and mother" work when you've been raised in an abusive household?
Harav Dovid Cohen shlit”a has stated [see addendum] that if interacting with an abusive parent makes a person emotionally ill then the child is exempt from this obligation. Since one is not required to spend more than a fifth of his assets for a mitzvas aseh then certainly one is not required to make himself sick. Obligating abused children to unconditionally honor their abusing parents will almost certainly exacerbate their emotional distress and/or disability and they are therefore, not obliged to do this.
