What is wrong with this person?

What would you do if you spoke to a family member about some relatives that disrespected you in your home? You spoke to your closest relative about what took place and they decided to take these peoples side instead. What makes you angry is that this person never had a relationship with these people at all, but was willing to agree to everything they had to say. Once they were told about this serious matter, they immediately called them for a ceremony that was being held and wanted to be a part of the festivities. The hint was given swiftly that they didn't want to be bothered with this person either, but they constantly called these people day after day so they could be a part of the event. Finally, these people called and confirmed that this person could come. When they arrived they failed to mentioned that they didn't have a hotel room for this person. That this person could stay in their room while the other guest were treated like adults with the luxury of being in their own hotel rooms. They gave this person the choice of staying in the same hotel room with them and the ages for these people are ridiculous because they blatantly were showing this person the utmost deep disrespect. This man is a nephew 40 years old being told to sleep in a twin bed next to their aunt and uncle of 60 years of age in adjacent to another bed separated by a table on the other side of the room. They were pleased with these people becoming chaperone's over him. What would you do if you were in this situation? It was like what ever these people said they were mesmerized by them, like as though they were in a trance.
