Domestic violence can traumatize a victim in a variety of different ways. It can leave them haunted by memories of the abuse. It can also leave them with a great deal of fear that the perpetrator may try to abuse them again. Fear and bad memories can sometimes make continuing to reside in the community they have lived in intolerable for a domestic violence victim.
Thus, one thing domestic abuse victims will sometimes do to try to get a fresh start to things and get themselves in a position where they can move on with their life is move to a new community. Sometimes, such a move will involve moving to a new state.
