@jay6, the support (I hesitate to use that word) you're getting is completely unacceptable. The elderly friend who I supported had quite a lot of input from SS and she was a self-funder.
I would write an email to the GP (or hand in a letter if there's no public email) listing the problems in bullet points and make it clear that without help you will be leaving and your husband will not be able to cope on his own. Give them a date. Make it clear that your husband will deny that he has any problems because he lacks insight.
Ring SS and ask for an email address to send a similar email to.
You may need to write to the head of SS or enlist the help of your councillor or MP.
In my experience, things can happen very quickly if the particular service (NHS, SS etc) wants it to.
If all else fails you will have to wait for a hospital admission when a social worker will have to speak to you and you can tell him/her that you won't provide any more care and will be away from home when he's discharged.
