Charlotte Bronte , Mr Nicholls and her last years

>Charlotte was dumbfounded when she was proposed to by Mr Nicholls.  She didn’t love him, and felt that they had nothing in common.  However, her father lost his temper when he heard of the proposal.  His motives were mixed. He was afraid of losing his daughter; he was an old man and wanted her to be with him and look after him.  He also believed that she was too delicate to endure childbirth and that marriage would be dangerous for her. He didn’t like Mr Nicholls much either. He believed that as a well-known novelist, Charlotte could do better, in finding a husband and that probably Mr Nicholls was boasting about his own family background in Ireland.  The man had nothing but a modest income as a curate…how could he keep a wife?
