Michael I am so sorry to hear your wife passed away. I hope you are managing to pick up the pieces and go on. I know it will be hard for you.
I had a conversation with my husband just before reading your post, and he explained all the reasons that AI in his opinion, is a no go. It's his background.
And now I have read your lovely story and it all fits together.
I'm a story teller. I could never pass someone's work off as my own. I'm unique, so too are you, and so are all the credible writers.
May you find peace in the new year. :)
