What is Frank's description of Rebecca and how does it make the narrator feel?

Regardless of the way he describes Rebecca, or the way he explains to the narrator that because of her modesty, sincerity, and kindness make her a far better match for her husband........... the narrator walks away from Frank feeling that even he was in love with Rebecca. He even claims that she was the most beautiful creature he's ever seen.......... so let's face it......... that wouldn't make an insecure, second wife anymore confidant that she was before their conversation.
