I have googled novels about emotional abuse in romantic relationships, but I wasn't sure what's good.
For films, wondering if anyone knows of any. I have seen 'Sleeping with the Enemy' with Julia Roberts, which depicts a certain kind of control (he gets angry at how she arranges the towels). But there are other kinds of controlling relationships too.
I once saw a drama called 'I am Nicola' on Channel 4, which was good on the manipulation element of a controlling relationship.
Was wondering if there's anything else out there?
