If you can figure out what her goal is - even if it makes no sense - you might be able to hit this situation with a bit of a plan. If these are relatively new symptoms if MIL hasn't been an attention-seeker all her life then I suspect that some cognitive or neurological impairment could be the cause. I managed to get all her pills away from her after she overdosed on an Alzheimer's drug. And I am going to have to remove her medications and only give her what she is supposed to take. Also losing his wife -- to a rabbit hole of servitude and gaslighting and going nuts trying to be the bigger person -- is optional. We had gone shopping that afternoon although she was in her wheelchair but getting out was a sign that things were looking up. She has never been like this, only recently has started this behavior. She was taking Metformin a few years ago for her diabetes. I knew mom wasn't thinking through the consequences of her new behaviors as they related to her faking symptoms of poor health but I didn't understand why - and why mom could not see reason when I explained the consequences to her.
