I think the following may just be the most unromantic proposal of marriage scene I have read:
'So Mrs Van Hopper has had enough of Monte Carlo,' he said, 'and now she wants to go home. So do I. She to New York and I to Manderley. Which would you prefer? You can take your choice.'
'Don't make a joke about it; it's unfair,' I said; 'and I think I had better see about those tickets, and say goodbye now.'
'If you think I'm one of the people who try to be funny at breakfast you're wrong,' he said. 'I'm invariably ill-tempered in the early morning. I repeat to you, the choice is open to you. Either you go to America with Mrs Van Hopper or you come home to Manderley with me.'
'Do you mean you want a secretary or something?'
'No, I'm asking you to marry me, you little fool.'
From Rebecca by Daphne Du Maurier.It's no wonder she had to ask what he meant.
And in case you were wondering: It doesn't get any better.
