Umm, if you know it was her, I hope like heck you have reported that to the authorities and she's cuffed soon. What the heck did you do to piss her off this bad. So glad I never had to deal with a crazy ex.
Just remember they are ex for a reason (both of them). Having said that I would report it to the local police and name her as the suspect. And yes, keep a pistol with you.
Trust me, the ex I started talking to again should of never been an ex. But yes, the crazy one and the gun have been reported to the police & I'm carrying my Glock instead of my lcp now
