Do you feel like your abuser is still hanging around you and watching you? I would say the best way for them to lose interest is stop thinking about them or your past relationship with them. The more you think about them, the more they are drawn to you, like a magnet. However If they have advanced to a point where they have regrets about how they treated you, then they might be around you to help you. it helps them to advance by helping you, by making amends.
