When I was dating my husband many years ago and about to meet his mom for the first time he told me " one thing you should know about my mom- she's 99% b.s. I was shocked, but found it to be true. My MIL of 35 years has an undiagnosed personality disorder. She constantly lies, makes up stories and according to her is personal friends with stars and related to just about anyone of royalty. We've gotten used to it over the years and have learned to ignore it.
More recently she's developed severe paranoia, agoraphobia, and anxiety. She believes people are breaking in stealing her things and accuses my father in law of violence ,having sundowners, and affairs, hiding her phone so she can't call the police on him, and stealing her jewlry. She has blocked all the entrances to the rooms in her house with chairs and boxes, and bunggy corded all the cabinets and drawers shut . She follows him around yelling at him that he is stealing her things and tried to hit him and he stopped her by grabbing her wrist. Being elderly this caused a bruise. She had him arrested and he was put pysch watch because she told them he's violent due to Alzheimer's! He refuses to stand up for himself and allow us to help. He says he can handle it. She won't go to the doctors ( anxiety, agoraphobia) won't let a nurse in the house.... Is there anything we can do or should we just wait until there is a major crisis. My father in law has his own health problems.we are so frustrated. My poor husband is soo stressed.
