Reading those two entries it is clear to me that the one written on May 22, 2008 was as much fiction as the ones written after she killed Travis. I have no doubt that she intended to use her journal to show that she had no bad feelings towards Travis and no reason to want to kill him. The other thing that is clear to me is that despite what she has written she is clearly obsessed with him, as much as ever. I admit that I haven't read her entire journal but what I have seen show clear obsession from the time she met him to after she killed him. Maybe because it is select entries? But it seems that all she ever writes about is Travis. Maybe there are other entries that don't have anything to do with Travis and they haven't been released because they have no relevance? It could be but what has been released shows how much she obsessed about him.
I also believe that those 6 weeks or so between killing and arrest were plenty of time for her to get rid of any previous entries that may have shown motive and replaced with her own fairy take of how good and kind and sweet she was to Travis even though he was mean and yelled and said bad things. She never showed on bad side of herself. Maybe she really just was such a liar that she couldn't be truthful even to herself but I tend to believe she rewrote history. Even writing about hoping that their texts and recordings and hoping they would never be revealed and it's too bad she never got around to playing the recordings for Travis. I think not.
