I have some speculation.
What if BL's parents learned of the LE stop and had had enough? They heard BL's side of it, and said, "We're not paying for that storage unit any more." If that was their last form of cash aid, they may have played that card - and pushed him to come home to deal with it. I can understand that. They might have been hoping to support a break up?
Then, BL talks to Gabby every day, makes up his mind to try again, but now there's an extra stressor for him (and he's already beyond his limit).
It's possible that when he comes back he doesn't tell them what happened. And then, after the missing person's report is officially filed and it all becomes national news, he makes plans and flees (through one way or another, to include feeling suicidal at having lost everything).
