We moved in with mom 4 months ago. Mom has not responded well , has anosgnosia, and confused and agitated by our presence most of the time . We had a incident where she screamed at us for creating a living space in her basement, our only area of respite besides the bedroom as she commandeers the entire first floor and sleeps in den where she spends 95% of her time . Husband LOST it, screamed back at her and has not looked at, spoken to, or acknowledged her in any way. I have been unable to help him to depersonalize her behavior. Mom has no recollection of this or any of her offensive behaviors and would deny if attempted to address with her as she lacks the capacity for reasoning or empathy any longer . I am caught between a rock and a hard place .
As others have pointed out, it won't get better, especially if she becomes incontinent, says or does vulgar things, shadows, screams for help continuously, etc. Been there, done that. I wish you clarity, wisdom, courage and peace in your heart as you make decisions.
I am sorry, but you can't change others. We all have our limitations; apparently this is your husband's.
Figure out what to do next. Taking care of mom is going to get harder, and your husband’s understanding will probably not grow. Is this worth losing your husband? Because that’s a possibility.
How's this arrangement working for you?
Stage 5 Dementia patients should be in MC. Why did you both decide to move in? I would guess to save rent money, be unpaid 24/7 caregivers, or both?
You aren't caught in any rock or hard place. Time to decide if your priority is your husband (and marriage vows you made), or your Stage 5 Dementia Mother, who you admit will "deny her offensive behaviors." This idea has already exploded in 4 months, and likely to get much worse. I cannot see convincing your husband of anything other than getting out. Sorry.
