Person A likes sleeping but has trouble staying asleep from time to time. They are quite particular about how they have the room (must be pitch black, cold room with white noise on speaker but no other noise)
Person B has chronic insomnia but recently has been getting better sleep due to new medication. Person B also has other sleep issues like thrashing and talking in their sleep which are not helped by new medication (but not made worse, just they are asleep for longer!) This sometimes, but not always, wakes A.
The current solution is that A and B sleep in separate beds in the same room but A constantly complains that they don't get enough sleep because of B and gets quite irate if they are woken up by anything.
B wakes up earlier than A and although they always need to do a wee, get a drink etc when they wake up B currently sits in silence for as long as it takes A to wake up, even if that means 4 hours of needing a wee, for fear of waking A and upsetting them. Obviously this is not a good solution.
B has suggested that they sleep in separate rooms, B would like this as they would be able to relax without bothering A no matter what time it is and feels that they would both benefit.
A doesn't like this idea as they like waking up in the same room as B and get anxious when they wake up and B is not there.
B doesn't know what to do now as on the one hand they care a lot about A and don't want to cause unnecessary upset but at the same time A's sleep is suffering and that in turn is impacting on their day to day mental health and their general relationship to everything, especially B. B themselves would benefit a lot from separate rooms and would probably prefer it but is more concerned with A's feelings than their own and wont change anything if A is not happy too.
There has to be an adequate compromise? Who is unreasonable? Is anyone being unreasonable?
