Girl's Behavior

I don't know why my ex gets infuriated when I ignore her or when I am indifferent towards her abuse tactics, infact I ignore her bullying on purpose?

And it bothers her a lot i am guessing, also i did confront her one day and told her to stop haressing and abusing me to which she said "if you get married as per your parents choice or with someone other girl then i will leave you" what the fuck kind of response is this from her? Why does it bother her if i am living my life while i ignore her? And why the hell should i be married to someone to free my self from the egomaniac ex of mine? Something tells me she's trying to hide something? Or she doesn't like seeing me happy with my self? Or don't want me to grow further in life? But yesterday she reported all my accounts on reddit for content violation, this way she's taking away my freedom, also she isn't letting no friend of mine talk to me and she's is way more close my co-workers than i am supposed to be, and she she doesn't work with me either, her attention is always on me, i don't why she's monitoring me so much? One thing which bothers me a lot is, she distanced particular set of friends whom them and i had similar passion and interests and we used to geek out on discussing on those topics, now she left me with nothing and wiped my happiness, also even when i am ignoring her after all this she seems to be not done infiltrating me?
