My husband is still a nice guy, but no short term memory and got lost driving. I have to do everything, but it’s ok. I just hope he can continue to shower himself.

My husband is accusing me of cheating on him, when I never did. It started about 6 months ago with truly outrageous accusations about my behavior. We would talk it out and he would say he was sorry - he believed me. This would happen every few weeks. In the last two weeks he has started accusing me almost every day and he forgets our previous conversations where we talked it out. It’s starting to really bother me and I don’t know what else I can do to help him (and me!). Any advice would be greatly appreciated.
