A potentially abusive partner will usually be a sociopath or a psychopath depending on the situation. Sociopaths and psychopaths have been known to feel empty on the inside. Which is why they treat people in their relationships like punching bags to make them try to feel something when they are eternally empty on the inside no matter how many fights, drugs, and sexual activities they get. These sociopaths and psychopaths have brain structures that are different from average people's brain structures. Psychopaths lack the brains to feel empathy and sympathy towards people compared to average people, which can make psychopaths aggressive, manipulative, destructive, coldheartedly calculative, and "socially" imitative because psychopaths are like cold robots who are only good at "socially" imitating people's social norms instead of empathetically knowing why those people have their social norms in the first place, which makes psychopathy part of the autism spectrum because psychopaths don't have the brains to be able to socialize normally, they're only good at imitating normal people who are able to empathize and sympathize normally. Psychopaths will usually detect that something is wrong with them and that they don't fit in with average people because of the brain abnormality in psychopaths, so they will try to blend in with people. They, the psychopaths, usually get into relationships with people to blend in with society. Psychopaths are more likely to get divorced and have abused significant others than be in longlasting relationships and treat their significant others with respect, commitment, empathy, sympathy, and so forth. Sociopathy is the less extreme version of psychopathy, but sociopathy is borderline autism. Sociopaths can feel empathy and sympathy, but sociopaths usually feel less willing to be compassionate, respectful, sympathetic, selfless, and responsible for their actions compared to average people. Sociopaths are also more likely to get divorced or have people reject them from their lives because of their sociopathic tendencies because they would want to have a stable family in the future instead of dealing with a destructive sociopath that wreaks havoc in people's lives.
