ITA. May 2008 is the month that Jodi's rage spewed over and she made the decision that she was going to kill Travis.
All of her actions during May point to the obvious premeditation--making plans with Ryan (alibi), the sex tape (blackmail--maybe for one last attempt to make Travis stay in the relationship), stealing the gun, making plans with MM & DB, using DB's sister as the alibi for being in SoCal (close proximity to Mesa), etc.
Her journals don't read as journals. They read as an attempt at journal entries & it's obvious to me that Jodi used them as a running alibi. She makes sure to say that she's fine with the break-up & she's happy that Travis found a woman he wants to marry (NO JEALOUSY). She's bending over backwards to let us know that she was not jealous--and JW brought that up, too.
So that means she was so jealous it made her insane with rage.
Jodi Arias is like a flea. She jumps to the nearest warm body and is always alert to which male is standing close to her present host, you know, for when she jumps. She is a sociopath and they do not love. They do, however, like to own.
Here's a pattern:
*Bobby is broke and starving. He lives in a hovel. She supports him and helps out his family. She is always broke.
*Matt is broke and unfaithful. He lives in staff quarters or a tent. They are both broke and help each other find seasonal work. She is always broke.
*Daryl is faithful and broke after moving to Palm Desert, buying her a house and moving back to Monterrey. She supports the house she lives in by herself by working several jobs. She is always broke.
*Travis is unfaithful and broke after spending too much time/money traveling with Jodi and lending her money/cars, helping her move, etc. She ends up as a pariah in the ward, unsuccessful with PPL and without Travis cannot go to any of the glitzy functions at PPL. She tries to fix that by going after a new PPL guy who is higher up the food chain than Travis, because she is so broke that she calls her mother to come help her move back. She's run out of men.
Only this time something new has entered the picture. Instead of being able to keep him on her charm bracelet like the other ex's, she has to take some kind of action before its too late. Travis is going to tell everyone that she has stolen money from him--even though she's been paying it back-- he's going to tell them that she slashed his tires, that she's crazy and has been stalking him and hacking into his FB, his myspace, his email.
Worse yet, he has threatened to report everything she has done to the police. What if Ryan hears about this?
She starts planning to ruin him first, so his credibility will be gone before he starts trashing her...she'll blackmail him into silence and she has to do it quick--he's given her a deadline.
And you know the rest.
