It just looked like young kids playing at being grown-ups. Like all of the women who go to India she wanted to be American and live American in India. TJ really should’ve told her what the marriage expectations were but he clearly knew she wouldn’t marry him if he said it so he didn’t. He was extremely selfish and is reaping what he sowed.
I’m also wondering what the year she stayed there before marrying him was like. I doubt she lived with them.
