Question:
Does anyone know of a movie...?
about a guy abusing a girl? thanks
Answers:
Are you talking about younger characters? (you said "guy abusing a girl" so I wondered.) If so, maybe "Fear" is the movie you're thinking of.
There are so many movies about abuse, we'd be here all night typing! Some of the ones I thought were good:
Bastard Out of Carolina
The Burning Bed
Waitress
