I apologize, I'm not trying to blame JC, I am just saying I wonder if the signs were there but she didn't trust her own intuition, didn't want to admit it, or felt like a failure, etc. and put up a front or built up a protective wall for herself. Again, she carries no fault here. What could she have done other than what she did already? She talked to him about his behavior and also tried to be around her more often, maybe subconciously she was keeping an eye out for something?
She was very young when she married Tad and has likely been through the wringer even well before he up and decided to run off with a girl he had groomed and persuaded to run away.
Also, I did say vaguely reminds me of Anna. Both of their worlds have been shattered by men they trusted. I never said she was the same and I don't think she will go back to Tad. Anna, unfortunately, is too indoctrinated and doesn't have much of an option, IMO. She doesn't even have the option to go to therapy without backlash from her family. JC has options and is hopefully taking advantage of them.
