Henry Tilney version of the love story from Jane Austens Northanger Abbey.

I read this book some year ago. It seems I did not register it than.
I read it again last week. I never really understand their attraction to each other. It does get a bit clearer reading Henrys thoughts, but still I do not really get it. And it is not that I do not like these two, I just thing it is an unequal couple. Will Henry still be that attracted, when Chathrine loses her naivity? Will he slove her, when she turns out not to be a very practical clergyswife? Well, I am pretty sure she will be a wounderful mother!

Read it again to try to solve the same question: Why does he fall for Cathrine?
