Re: She doesn't think that Edmund is wrong for her.

I don't know where the author is going, but it seems to me that he is wrong for her. You are correct, in that she thinks she is wrong for him - and she is wrong for him, because he is not looking for a strong woman who slays demons. He has no discernment about Miss Crawford, whereas Frankie is able to discern demons, Possessed, curses, etc. I hope she finds a husband who is able to help her either as a fellow demon-slayer, or as a helpmate who supports her in her work. Does that make sense?
