Something else about the world they live in that comes through in the way the characters behave is how comfortable they seem to be with darkness and being alone.
That being said, it is even more difficult to deal with Ellie leaving Dina all alone on the seemingly secluded farm, in a big home, with all the animals and work, caring for JJ. She didn't just leave Dina. She left Dina with full knowledge that it would be impossible for her to wait for her under those circumstances.
Ellie and Dina Spoiler warning:
I think Ellie feels guilt for spending the night with Dina, when Jesse told them that Tommy and Joel didn't show up.
I think she feels like she might have been able to find them earlier than she did and possibly even saved Joel if she weren't distracted during her time with Dina that night. It very likely contributed to her decision to go find Abby one last time, leaving her life with Dina behind - she might feel like she is partly to blame and must make it right. That she didn't really deserve what she had with Dina because it cost her Joel. That's why she left, in spite of her fear of losing Dina - her guilt was greater.
I suspect Dina really did smell like a hot pile of garbage after dancing and being sweaty at the church. No way they had deodorant in that world.
