Why would she feel the desperate need to slap him?
There is way more to the situation that caused GP to slap BL:
Rose Davis has claimed her fiancé Brian Laundrie, 23, was a jealous and
controlling partner in their relationship.
BL
stole Gabby's ID so she couldn't go out with Rose.
BL later
tried to stop them from hanging out and being friends.
The two were such good friends they even shared their locations with each through an a app, but when Laundrie found out,
he made Gabby delete it.
He'd demand she be home for dinner, often cut their time short.
He'd demand to pick GP up from her house, even when she had a car and offered to drive.
Rose, who knew that her friend suffers from anxiety, said 'for her anxiety to act up like that, there has to be a decent thing to trigger it. Something had to happen, or just a lot of things had to build up.
