This is a familiar pattern of behavior for Jodi IMO. I think Travis was most frustrated by this part of her personality and those times he was yelling and cussing her it was an attempt to garner some sort of normal human reaction from Jodi. He never got that which is when he realized she was a sociopath, not good for him, and he tried to end the relationship.
this behavior reminds me of how she acted in that video when Travis was telling the story about that dream....she was so not paying any attention
