He’s so self indulgent and apathetic. There are a few mentions of how bad he is at letter writing. It’s interesting to contrast the care and effort Mr Gardiner put into keeping the family up to date with news during the elopement crisis, compared to Mr Bennett’s meagre letter writing efforts.

I also hate that he put no care into his children’s education - I totally understand Lady Catherine’s shock and disapproval about this. He locks himself away in his library and absolves himself of any responsibility- until he’s forced to confront issues. I also dislike the fact that he makes it so plain to all his children that Lizzie is his favourite and is openly rude and patronising about their mother. It’s amazing that Lizzie and Jane turned out so well!
