Her crazy didn't just come out of nowhere and blindside that nikka. There had to have been warning signs, but the nikka probably thought nothing of them because he was getting the draws. Now out of the blue he has decided to notice the signs.
Be a man and just ignore her bullshyt and she will eventually go away. If she doesn't go away then understand that stalking is real and eventually she will fugg you up or have someone else to fugg you up so get a restraining order. If you catch her violating that order or committing another crime then turn her ass in.
