To me, this is just another artificial construct of our enigmatic culture that we are expected to accept, regardless of what our independent thought provides us with. I don't understand how remaining around anyone, regardless of DNA relations, that is apparently toxic to the relationship, is beneficial to anyone involved. Instead, we struggle to maintain the pseudo connectivity to this individual(s) to keep up appearances in the public eye. Meanwhile, drama ensues as a result of one trying to please the other in a circus-like fashion, with the only conclusion being psychological damage to all parties involved. I think you should surround yourself only with the people you have a distinct connection with, but also respect everyone, regardless of how you interact with them. I have an incredible relationship with my immediate family, but I rarely associate with my indirect relatives. Does this mean I don't like them? Of course not! But, I do not feel any reason to associate with them, since I have no direct reason to socialize with them at all. If they needed my help for any reason, would I happily oblige? Absolutely!
