I think there can be different manifestations... I think it can vary. I've never heard of a complete memory loss (as JA describes) associated with PTSD, but I can't say it isn't possible.
What I want to know is... WHAT traumatic event/events?
The only traumatic event in her life (it appears) happened on June 4, 2008 - at her hand!
Guaranteed they are going to say JA 'acted out' sexually to comply/pacify... ugh - that's going to be a tough day. They're probably going to say Travis' ongoing controlling behaviour did... something to her - who knows. Even if that story were true, it'd still be illegal to kill him. So scratch that.
Remember - they lived in different states for the entire time they dated, and the majority of the time they knew each other. They didn't have as much contact as the DT is trying to imply.
Most of their relationship, it seems (bad or good) was over the phone... (and text/emails). They were hundreds of miles from each other - except for the time she lived in Mesa - and that's when she did her stalking stuff, so Travis was clearly dating other women. I don't think they saw a lot of each other even then...
smoke and mirrors.
