When do you decide that enough is enough? How do you know when
To end a relationship that in fact is not a relationship - just one sided.
In this case, it is a parent/adult child relationship with the child being

Just how much poor behavior and lack of disrespect does one accept.
It's hard to decide to write off a relative.

How old is the child? 7 or 21 or 47? That will make a difference on how people respond.

How is the child being vindictive and unstable? Could you tell us more and give some examples?

How has the adult reacted so far, if at all?
