So she's finally accepted it. She doesn't love her husband the same way she loves her boyfriend. It's only a matter of time before Felix finds out, especially if Sophie gets even more reckless and stops caring about him even more. Everything seems like it's about to come to a head.
I gotta say, you've made me care about these characters more than I thought possible. Watching Sophie slowly turn into a different person while Felix's world crumbles around him is one of the most interesting stories I've read. I'm way too emotionally invested, and I want to see where this goes.
