What I think it means is that she didn’t really try to understand the expectations on her to be TJs wife. She moved to india to be with TJ for one year and didn’t glean enough information into how traditional his family were and what was expected. However in her weak defence, TJ said he was purposely avoiding that topic to the point of almost being deceitful. They’re both awful people. TJ should have known his parents were too traditional for his American wife and she should have known TJ has zero backbone.
To be honest, the problem is in Indian culture there is a very strong belief that shit will magically right itself after marriage. I’m not even sure what Kim thought would happen moving to india where she had made no friends and learned no language despite being there for a whole year.
