Right now your first duty of care in to yourself, as @Bobbi has already said. And that goes for all carers who may read this, because who would look after their loved one if they are seriously incapacitated as a result.
You did the right thing, it doesn’t matter how much support you have around you, because at the end of the day its still just you and him, without a break.
Just what is good support. We thought we were being very supportive of my mother-in-law with my father in law when he had Alzheimer’s. Until the day she learnt she had pancreatic cancer, then the whole truth came out. It had to didn’t it?!
The trouble is your support are not mind readers, so if you are putting on a cheery confident happy face in front of them, your public face, but not telling them exactly what is going on in your head, your giving them a false impression. People will hold back for fear of offending you. The last thing they want to do is give you the impression they think you can’t cope or are not doing a good enough job caring for your husband. You know, there’s a very good reason why mother nature gave women a cut off age for having babies and this is it!
What age is he, could he already have onset vascular dementia/Alzheimer’s and the stroke has escalated it, strokes are common in people with dementia. The more I re-read your post the more I’m inclined to be believe that is the case. The articles below will explain better than I can, the 3 stages of dementia, early, middle and late stages of dementia. But ignore them if you already have too much to take in 
The main question is, do you have someone to advocate for you because there is a lot to take in going forward and you could really do with a second pair of ears to catch what you may miss, to understand where you don’t maybe. It is both a stressful and very emotional time and some hard decisions have to be made, what’s best for both of you.
Keep talking Lilers, we are good listeners here with a lot of useful advice to support or point you in the right direction. And again, give the Stroke helpline a call, they can even match you with a volunteer caller for some one to one chat with a fellow carer. Don’t just “take” all the help and support you can get, actually use it to your to advantage, otherwise its just a waste of lip service
