My boyfriend's ex has been causing him and myself grief. They've got a lot of legal stuff going on themselves, but I want to know is what I can do for myself. When she doesn't get attention from him, she finds a way to contact me and emotionally hurt me. And I've had enough. She'll hack all of his social media accounts and she somehow sends me messages off of his number even when I am with him - so I know it's not actually him. She used to call me off of her own number; I'm still dumbfounded how she got my number in the first place. Most recently, she messaged me stating my parent's names in a text sent from his number. I don't know how she found that out - perhaps on Facebook through another account (I've blocked her and all known hacked accounts). She also has multiple phone numbers and I believe she has called our family home phone before. She calls, doesn't say anything and then hangs up. She has also come around to his house, let herself in and stolen items of clothing (however, I can't prove this). I now also have to hide my car when I visit him as she stalks the house. Previously she has thrown paint filler from the back of my boyfriend's ute all over the windshield of my car. Is there anything I can do to get her to leave me alone under Australian Law? I've had enough of the emotional torment. I feel like she always finds a way to contact me.
