Yes some can, but they will never truly leave their "victim" alone. It's a form of mental abuse. The victim usually finds it very difficult to be on their own or, they are terrified their abuser will actually come back into their life. Abusers love to "put down" their victim and make them hurt. Abusers can have several women in their lives (he may not abuse all of them), but, because of their abusive nature they know they can always come back into the victim's life and they do! Only the person being abused can stop this cycle of abuse.
