in denial

Last year my LO attempted suicide. Totally unconscious while in ICU she would go on for hours of delirium about how much she hated me. Called me names and wouldn't stop. Drs all said it was unconscious and she doesn't remember any of it.

It still makes me cry and is hard to forget. Why? Where did it come from? Hard to believe she didn't mean it on some level.

I understand and am very sorry this has happened to you.

There is a reason fear and anger are often mentioned in the same sentence. When he can understand the diagnosis it makes him afraid and it is a common reaction for people to strike out in anger when they are afraid.

Most of the time he probably cannot understand. It is not that he cannot accept, he cannot see any problem, so when you say there is one he thinks you are lying. No amount of proof will help. This is part of the disease and the term for it is anosognosia.

There is a good channel on YouTube called dementia careblazers. It has a couple of helpful short videos on this.

The need for him to accept the diagnosis is your need, not his. Let it go. He does not need to accept a diagnosis for you to do what is necessary for his care, and your life will be more peaceful. As others have said, look into medication if necessary, FTD is hard.
