H is desperate for anything he can use to justify himself. Your aunt trying to reason with him cements his "story" and your friend trying to get a rise out of him (!) fed the story he created in his mind that he's doing nothing wrong. You cant make him believe your truth, you can only detach. FB is like crazy glue for the LBS, gluing your thoughts and feelings to the minute airbrushed details he chooses to broadcast. And some friends and family like playing out drama. It is all unnecessarily hurting you, no good can come to you from anyone paying attention to his FB activity.
