In matters closest to the heart does Anne act in an irrational manner ? When Capt. Wentworth visited Uppercross Cottage she battles overwhelming feelings. He makes her heart beat faster but she endeavours to calm herself, by attempting to blot out feelings with reason.
At Uppercross, Anne and Capt. Wentworth find themselves 'repeatedly in the same circle'. Generally she is tomented by 'His cold politeness, hs ceremonious grace'. (Ch.8)
Such a contrast to their relationship of eight years ago.
I do think Anne's emotions and reason are not integrated at this point; yet she does not appear to run off or not face up to Capt. Wentworth. She does not lack for moral courage.
Anne does not seem not reserved or shy. She talks quite easily with people such as the Admiral and Mrs Croft. She befriends the grieving Capt. Benwick and engages him in critical discussion of literture. (ch.11) Anne may recognize a parallel between herself and Benwick; each is enduring the pain and loss of a loved one.
Conversing with Benwick, she tries offer helpful advice to the melancholic young man. IMO, this shows not only sympathy but an attempt to transform her own suffering to a positive end for her own consolation.
Interesting to wonder if Lady Russell would have approved of Anne and Benwick's friendship at Lyme.
I don't think Anne is too good or 'perfect' readers cannot empathize with her charecter or situation.
