Im sorry

The need for control is a major symptom in FTD. Their executive function is failing and they know they are losing control, but they dont understand why and think its because its being taken away from them. OH constantly tells me Im taking him over and preventing him from doing things - he just doesnt understand that he simply is unable to do them any more and is desperately trying to hang on to the things he
can control. The threat of divorce is also really common in FTD, I think it is because they are trying to provoke a response - my OH told me in a lucid moment that he could no longer access his emotions and it felt to him that everyone and everything was emotionally distant from him. This insight didnt last long and within half an hour it was back to me being at fault, but I found it enlightening to me. I think a lot of it is him being like a small child stamping his foot and saying "I HATE YOU!!" when he cant get his own way.
Not that understanding it makes it easy - it is still my OH looking and sounding like my OH, but saying horrible things and behaving in a way that he never would have. Im sorry, I dont seem to have an answer and have just gone on about myself. Sending tons of empathy ((((((hugs)))))
PS - I had to smile about him realising that your phone password had changed and wanting you to change his too. If he goes on about it you could actually do this - do it in a way so that you know what the new password is, but dont let on about this and it may not actually occur to him that will know it
