Why is my ex who left me still trying to sabotage my life and dating?

My ex was the one that decided she no longer wanted to be with me and now that she no longer lives with me , she still tries to sabotage my life. I know she is mentally insane but why bother me if you no longer want to be with me? Why does she care if I am dating someone else, when she clearly has been doing shady shit before and after we separated. I have asked her what her fucking deal is , and she takes no accountability for her actions and behaviors whatsoever. She is running around like she is this victim when she is clearly the villain. I never had an ex that wanted to end things with me that decided to continue bringing havoc into my life. The girl needs her fucking ass kicked. I have tried being mutual with her because we have kids’ together and she still starts shit with me. So my only option is to move far away from her crazy ass once the house sells. I don’t want to get the cops involved because I already experienced that shit on how the cops favored her crazy ass when she attacked me first while I was sleeping and then I end up going to jail. So cops are not the solution , I ignored her phone calls and texts which just pisses her off even more. I asked her what her fucking deal is that I am not her convenience, she also got upset with me because I no longer wanted to sleep with her anymore because I knew it didn’t mean anything but just getting off on each other. I told her I don’t want to sleep with a girl that doesn’t want to be with me 100 percent , I don’t want STD’s especially if she is screwing other guys’ and if I meet a great girl , I don’t want to do that to her either. My ex is going through menopause on top of her mental illness and I told her she needs to go get help immediately , but she turns everything around that I am this bad guy when she is clearly the bad one. Have you ever had an ex do this to you?
