Similar situation here; sorry long one. DF cares for DM. DM has carers 4 x day and they love having them turn up to help. So I've been lucky that they have accepted help in that respect however, I asked SS to come and see them in the summer and get DF to agree to respite care (apparently he's entitled to 3 x weeks per year). DF initially agreed with me that this would be a good idea so I set up the meeting only for him to say 'no, absolutely not' when the SW asked the question about DM going into a care home for a week or two to give him a break. I nearly punched him.
Anyway, roll on to October and what happens? DF falls ill, is taken into hospital for 8 days so I move in with DM and care for her but I call SS on the first day of me being there saying we need to organise emergency respite as we don't know how long DF will be in hospital for and I cannot care for DM indefinitely. It took SS 6 days to arrange 'emergency' care. 6 long fucking days. I was spitting blood by the end of it and when the SW said 'can you last another 2 days?' I said an emphatic 'NO' and burst into tears. She then said 'any friends/neighbours/family could pop in and look after DM?' I just stared at her in disbelief. Who the fuck wants to take on the responsibility of a woman who's Type 1 diabetic, doubly incontinent and needs hoisting every time she needs to be out of bed?!
And the icing on the cake? I was told "If you can't cope, take DM to a local hospital A&E department and have her admitted as a social admission". So effectively abandon her to the system and walk away. But SS KNOW people won't do that so they drag their bloody feet, kicking and screaming before getting to a solution. I involved fucking everyone in my complaint, the local MP came up trumps tbf.
So respite care was arranged, DF came home and was able to potter around without worrying about DM for around 10 days. He's adamant now that he will take the 3 weeks per year but all this happened because they failed to agree to respite in the first place!!! All because DM said 'but we promised each other, we wouldn't put each other in a care home'. And according to DM that is now the law.
