Hi hoser, You have done nothing wrong. Why condon toxic peronalities in your house? Get rid of them from your life. You can choose to continue to be bullied by them, be polite to them but make them feel uncomfortable, ask them to stay in a local hotel if they do not respect your decisions/opinions, etc.
If they try to bully you, just show them books by Raymond Franz (i.e., "Crisis of Conscience" and "In Search of Christian Freedom"), Don Cameron (i.e., "Captives of a Concept"), and/or Steve Hassan (i.e., "Combatting Cult Mind Control", "Releasing the Bonds: Empowering People to Think for Themselves", and (i.e., his latest book) "Freedom of Mind: Helping Loved Ones Leave Controlling People, Cults, and Beliefs"). Once your close relatives see the books, they should run away and never bother you again.
Peace be with you and everyone, who you love,
Robert
