Surely, "The End" is a typo?
You've just started! How about 3-4 more chapters? One from her POV, showing how she appreciates having her opinion truly heard and how she observes Tom taking her advice seriously and trying to improve himself? (It would be flattering for any person, knowing that they have so much influence over another.) Some quiet nights playing cards and discussing freely everything under the weather? And starting to realize that being indispensable for one's happiness trumps being the consolation prize? (I am not against Edmund/Fanny, but JA left too much for my imagination to not see their story as the "good enough" couple. I always want to be convinced that Fanny found a person that fully appreciates her and Crawford could not be that one as one little wiggling finger of Maria made him focus on his hormones and forget Fanny.) And then a conclusion where Fanny is truly happy in her marriage, while Edmund starts realizing that he should have focused on her and not Miss C and finally maturing a bit in this respect and eventually finding a truly amiable woman to learn what true love is? Just 3-4 chapters of goodness and some character growth for all three
(And as I'm on a demands-mode, let me also demand that you deliver in less than 2 weeks. I'm then due! :-p )
