Ah yes, the prison of care…
It boils down to three questions.
(1) Is your mum in PHYSICAL danger of any kind not having ‘someone’ in the room with her?
(2) Is your mum in EMOTIONAL DISTRESS if no one is the room with her?
(3) Is your mum in EMOTIONAL DISTRESS if YOU are not in the room with her?
Because what you can do depends on what the answer is to the above.
If the answer to (1) is ‘no’, then of course you can leave her, ie, she won’t come to any physical harm.
If the answer to (1) is ‘no’ and the and the answer to (2) is no, then, again, you can leave her. OR, ‘someone else’ can be with her.
But it’s if the answer to (1) is no and to (3) is ‘yes’ that the problems start.
For myself, I personally think that if she is in ‘emotional distress’ if you are not in the room with her as much as she wants you to be (which is???), then I still think you can leave her.
Of course we don’t want someone to be in emotional distress, BUT it depends on what we have to do to ensure that! If it means spending years of your life as a ‘prisoner’ just to ensure she is not in emotional distress then that is just not fair on you.
I would say that putting up with you NOT being there all the time is just part of ‘the deal’…ie, in exchange for having you there MOST of the time, she has to put up with not having you there SOME of the time (and then it is only a question of deciding how much is ‘some’!)
BUT I don’t think that the principle of her being in emotional distress at your absence per se, is justification for her having you there as much as she wants. We don’t get everything we want in life, and she doesn’t get you all the time.
BUT again, all that can go out of the window IF your mum has dementia. For both good and ill reasons. The ‘ill’ reasons are that she will have no mental ability to understand ‘the deal’, and that she will have no idea that you are only away from her for a set period and you will indeed be coming back to her. Like a baby or a dog, if she can’t see you you aren’t there…and she doesn’t know when you’ll be back.
Eventually, though, as dementia progresses, that inability to tell time tilts in your favour, as she will simply ‘forget you exist’ the moment she can’t see you, and won’t know how long it is since she last saw you…
It can take years to get to that stage though.
Overall, do you think that it is YOU she wants, or just ‘someone’? If the latter, then simply having ‘anyone else’ there could give you the vital ‘escape’ you need to keep any sense of sanity at all…
