You guys make some interesting points about "love." I think that's a real hard thing to pin down:
1. What is love? People define it differently. When I see Chartley talking about love, I see his description as more of a friendship that has romance intertwined. I wonder if he's really gotten to the kind of love that Granger has experienced with Travers, Calvert, and Cavendish.
2. This era was renowned for people falling in love quite often, so it's period-realistic. I think that maybe there's something to that, what with the lifespans being short. I mean, you didn't have all that much time to figure it out. Shit, most of us would already be dead if we were alive back then. Did that make sense? I think this is Granger's flaw, where he confuses infatuation with love, and dives right in, then has to figure it out later. Lucky for him, he's usually gone by the time it wears off, so it fades away naturally. I think his big challenge will come when he develops feelings for someone and he's in a position to take his time, like say when he's at home for an extended period.
