Did Robert give Mrs. Ferrars the idea to cut Edward off and out of the family?

My mother was the first person who told me of it, and I, feeling myself called on to act with resolution, immediately said to her, 'My dear madam, I do not know what you may intend to do on the occasion, but as for myself, I must say, that if Edward does marry this young woman, I never will see him again.' That was what I said immediately, -- I was most uncommonly shocked indeed! -- Poor Edward! -- he has done for himself completely! -- shut himself out for ever from all decent society! -- but as I directly said to my mother, I am not in the least surprised at it; from his style of education it was always to be expected. My poor mother was half frantic." (Ch. 41)
