Responsibility is always two ways. You always share responsibility equally with those who you are connected with.  

If by chance you have taken on too much responsibility you may have robbed someone else of the inherent personal power that comes with taking ownership and being a custodian of that which they own.  

Work diligently to protect the boundary between you and others. Especially those boundaries that allow for, maintain and negoiate what we will take ownership over and what we will not.
