How can I get my husband to accept care from anyone other than me?

He is just 1 person in the household - your wishes are important too - so maybe you tell him there will be some assistance coming into the house 

It is not up for discussion at all but you have several options so he can help pick which would be the least disagreeable to him - then give him 3 or 4 choices to pick from - let him know he is to co-operate otherwise you will have to add more from the list

Let him know you still love him & care for him but that you are getting older too - this help is really for you to be able to stay strong & healthy so that you can be there for him as much as you are able however you are human not superwoman so you need help to provide the best care for him

If he whines too much about this then ask him where he will be when you get sick & are in hospital - he most likely still sees you in his mind's eye as a young active person [about 40 years ago] so may not realize how much you need a break sometimes

Believe that you are making the right decision and move forward with your plans. Make it clear that this is about you and what you need.

Lillian, have you been able to get some help to give you a break?

Please let us know how you are doing.

If nothing else you can come here and vent to release some pressure until you get help.
