Denial on part of patient.

My husband was just diagnosed with Alzheimers. For the past 5 years thy called it Mild cognitive impairment. My biggest problem is that he is in denial about it. He says there's nothing wrong with him except he is 83 yrs old and he had a closed head injury when he was younger. His memory issues are classic. Continually asking the same questions and not remembering what happened 15 minutes ago. He reads but he can't tell you what the article or book is about.
I want to go to support groups with him but he refuses to go. Instead he insists on going everywhere with me and I have very little time to myself.
Anyone else having this issue and how do you deal with it?
