I know it is wrong to speculate about their mental health, both of them, because we don't know them and this is confidential information.
However, the police report is public info with some redactions, and apparently GP and BL both reported their self-diagnoses to the police. We don't know at this point if their diagnoses were medically valid, if they just conjured up these diagnoses so the police would not arrest them, or anything in-between.
What we DO know as a fact is that Gabby said she was afraid he’d drive away and was desperate enough to climb through the driver’s window and over BL to get back into the van.
So, avoiding any diagnosis that comes to mind (which are several), I’ll just say again that what appears to be a blissful love affair of two free-spirited people was anything but that. If their van life, yoga mindset and carefree existence was how they planned to make a living online, these personal problems certainly would put a halt to that.
Could the potential of not gaining followers and subscribers be a catalyst for disaster? Who knows? Brian does! Speak, Brian!!!
I believe
@SuziQ mentioned that a lot of young people hitchhike in Moab, sometimes with strangers. It’s also possible that GP and BL separated and she went off to hitchhike and met a bad end that way. That happened to high school friends of mine (Mitch and Bonnie, still missing since 1973, there’s a WS forum about them). It’s possible but not what I believe happened. That’s because BRIAN needs to SAY SOMETHING! Even if she hitchhiked with someone evil, he can still tell her family where he was last with her, and he should be drowning in tears that she’s missing.
