Perhaps it would be worthwhile exploring the options available to you, as traveller suggests?

I guess perhaps your husband is thinking about this in terms of money, rather than your care and sense of security. If you talk more, perhaps you can help to reframe the discussion for him so he can see it from your perspective. Money-wise, is there any way you could make things a bit easier for him to take it (things to sell, budgeting?).

I hope you can find a way to feel safe and happy with your care
