My MIL has moderate dementia. Yes, she is a narcissist, negative, and nasty like so many others. She has fought with every neighbor she has ever had and is even mean to medical people. She has embarrassed us at restsurants, with doctors and at stores trashing people. She gives gifts away that we buy her. We've tried to make her life easier with comfort things but she throws them out. She did not want my husband to marry later in life since she lived with him at that time so the relationship started fractured with her refusing to shake my hand. Now she has dementia and is worse but there's no one else to take her in. I know she will eventually qualify for Medicaid for a nursing home but right now, the dementia symptoms are getting worse and she may not be able to live alone. While I cringe at the thought, should I do the right thing and move her in, try to overlook the personality disorder, turn a deaf ear to the complaints, ignore the nasty comments and lies, and be a better person than I am now? I feel awful in that so far, saying no to have her move in. Would it be the right thing or am I considering it just so I feel better about myself? I am so conflicted and stressed. P.S. There is no money for an assisted living facility and she won't have a home health aide in, meals on wheels or consider adult daycare.
If you want to do the right thing, then assist your mother to find a permanent facility to care for her.
It's not about you being "a better person" or any such hog wash.
It's not about YOU.
It's about her. She needs three shifts of rested, young, TRAINED caregivers who can let her insults slide off their backs because they get to go home at the end of a shift.
Has she been seen by a geriatric psychiatrist? Sometimes meds can mellow folks like this out a bit.
But no, do NOT take her into your home.

Do not move her in. It will ruin your life if not your marriage. Folks who have sweet parents have moved them in and it turns out to be a disaster. You already know what her personality is.
Consider an assisted living facility. Does she own her own home? If so, sell that to finance the assisted living. With her dementia she won't be able to remain in assisted living, she'll need a nursing home eventually.
This woman sounds horrible. I pray that you don't move her in with you. It might be the biggest mistake you'll ever make.
