I've just come across this thread and I love it...someone has invaded my husbands body to be sure...he hasn't got ftd, got bulbar als, but he is not the same sweet man who proposed to me on one knee alongside a canal, with five ducks for witnesses...
I particularly can identify with what you say Hangingon1, about the fixation on trivia that can go on and on...and about behaving when others are about...
I am learning to 'let it go', 'get over it', even when its not my fault cos its a damn sight easier than reliving the same scenario for a what can be several hours, and just when I think it's died down, he'll stoke the fire with comments again...grrrr, gimme strength...and patience, I'm only human...
