stardustandroses Thanks for your response.
It is horrible. No, Dad doesn't know as he's so frail and poorly I try not to let things show and I'd hate for him to feel that I'm 'suffering' because he's here. I can't say H and Dad get on or not because H is so wrapped up in himself and his own interests he only has the briefest exchanges of conversations with Dad. In same vein, I wouldn't put Dad through another move. I really am not wishing anything on him, he's a lovely man and I love him to bits, he's my Dad and he's been through a lot, but when he's gone I will leave even if I have to go into a women's shelter.
H has become impossible to deal with. Arrogant, rude, unkind, disrespectful - the list does indeed go on. Yes, I have asked him if he is happy with the situation and he said no, things could be better. I've also told him that I no longer have feelings of love for him, as that died a long time ago due to his unreasonable behaviour and attitude toward me. I've told him I want a divorce and do not wish for any future that includes him. I don't know what else I could say to make my own feelings clearer. He just says he doesn't believe me, doesn't agree that the situation is as bad as I make it out to be, and doesn't accept that our marriage is over. So arrogant. Pompous. Unbearably and insufferably dismissive.
I'm glad your own H is amiable and puppylike, but do appreciate the wounding caused by lack of consideration and validation and am sorry you are experiencing that awful state of living as though you are invisible.
I feel responsible for Dad, not H. Dad came here rather than go into a home because I promised I would look after him for as long as I can. He nursed Mum at home for many years until she had to go into hospice and died there. He has a mortal fear of going anywhere like that now.
I haven't worked in some years due to failing health myself so no personal income or savings. No siblings.
So many of us in the same situation...
