You've been watching too many soap operas. In the real world there are a LOT of girls out there who are at times scared by or intimidated by an aggressive, controlling boyfriend. And yes n when they go back to being nice they snuggle up with them in bed like nothing happened. This happens in every town of every country in the world, every day.

Being scared in an intense moment that shocked her doesn't necessarily mean immediately running a mile. That's just not real life.

Even if she is an actress and is that callous - she must be wondering how it's been perceived out here, how its going to affect her when she leaves, if she's been painted as the abused woman... it has to be playing on her mind, either way. So if she seems carefree... that's definitely an act.
