I worked with his ex-wife years ago and she, myself, and at least one other person in the office all had restraining orders against him. He beat her and cheated on her regularly, while accusing her of cheating with every dude she spoke to. After she left him he stalked a few of us, but I got it the worst. He reached out to anyone who had a mild connection to me on Facebook, posing as a potential employer or distant relative, to get as much info on me as he could. He tracked down my apartment, he got my cell number. He sat outside my apartment for 2 days once while texting and calling me to come outside and "take my punishment like a man", luckily I was out of state at the time. I'm also fairly certain he tried to break into my house one night.
I got hundreds of harassing and threatening texts and calls. Do you know how mentally draining it is to wake up every day to 10+ death threats? Do you know how unhinged your threats have to be to make two defense lawyers say "holy shit" as they're read out loud at a restraining order request? Once the restraining order was served they didn't stop, they just came from spoofed numbers and people who did it on his behalf. On mother's day, I got 15 or so calls and texts all claiming to be from various hospitals or police departments saying my mother was dead for various reasons.
It's been over 6 years and I still don't leave my house without a knife or gun on me.
