I think he went home (to empty storage unit) because they decided to break up!
Now did she ask him to come back?
Did they do this often?
After the restaurant argument did he leave
Her there abd hitch a ride offering the person 200 bucks? Did he then get a text message from her asking him to come back
This is probably when they had their last fight! And she dies!
Just another theory among many!
maybe he left every time they had a fight and she would call him back!
I wish they had the phones it would explain a lot I think!
My first thought--and still prominent thought--is that he flew home because they broke up. Then, JMOO, he moved his stuff out of the storage shed that they shared, but probably left her stuff there.
Flying back to her was extravagant, so I can't help but think it was for one of two reasons--either to get back together and make a better effort--or to kill her so if he couldn't have her, no one could.
The reason I think the second scenario isn't all that farfetched was his very disturbed mindset at the Merry Piglets (or whatever its name is). That repetitive coming and going seems very much like a man on the edge. Perhaps he had mentally committed to killing her but emotionally he was a wreck.
It doesn't sound as though he had very many female relationships, so he might not have been able to see himself with anyone but Gabby. Of course, that's all MOO--I'm certainly no expert.
But, when my husband was growing up in Colorado Springs, he occasionally played with a little boy who live a couple of blocks away. He never went in their house, but the mother came out and would give them treats. One morning, my husband's parents sat him down for a talk. They explained that the mother had drugged her children and her husband and when they were asleep had shot them all. Then she shot herself.
I just sometimes think people view the world as too challenging, painful, and difficult for themselves and for their loved one. Perhaps, he was planning a murder/suicide all along but couldn't actually kill himself until a few weeks later.
All conjecture on my part.
