OK, I'll take the challenge.

What makes you think she is perfectly content with her new life? The two of you were in a pressure-cooker the whole time you were home. Why do you need to lawyer up right away? Maybe she was being honest with you that day. You have everyone telling you she was BS'ing you, and she has her group saying you are too rigid, and as long as the two of you listen to everyone but each other, there's no way of figuring out how you really feel. Why not talk to her quietly and honestly?
