Has any Lady here been stalked by their Ex ?

If you have been a victim of stalking, what are the stages of Stalking?, as it started out as little things, now her Ex is banging on the house at odd hours of the night and wakening her and her new partner. Its no good calling the police because there is bush land behind their house and they would never find him. Is this the worst of it? or will it get worse?. She is installing sensor lights to help deter him from doing this. Any advice would be very much appreciated Thanks.
