Often, an 'abusive hero' could be verbally abusive. He might say mean things to the heroine during arguments, which can be really hurtful. However, in some novels, this is part of the 'bad boy' image that the author wants to portray, and later the hero is redeemed through the power of love. But this still sets a bad example in real - life relationships.
An 'abusive hero' in a romance novel might show controlling behavior. For example, he may try to limit the heroine's interactions with other people, like her friends or family. This is not a healthy trait but is sometimes used to create drama in the story.
Another characteristic could be possessiveness. He may act as if the heroine is his property rather than an equal partner. He might get jealous easily and overreact to normal social situations. In a good romance novel, this behavior should be addressed and the hero should grow to become a better person, but unfortunately, not all novels handle it in a proper way.
