Craziest person you ever dated? Not met but dated.

The only guy I met from tinder🥲
I was with him for 7 months. After I broke up, he sent a man to my house (this man literally went into my apartment, cause my door was open) to check what I was doing, he texted me asking why I was sleeping with the lights on one night that I fell asleep watching tv, he would text me and tell me that he was watching me, would show up at my house or work. He quit his job as a nurse and started working for google, then hacked my google account. He texted me asking why I needed a lawyer after I googled lawyers in my area, and when I asked how he knew he just said that google knows everything. He hacked my fb account and re-posted an old photo, several years after I broke up (after I got married to my husband). Every time I blocked him somewhere he would contact me from another app and even sent me an email to convince me that he had changed. Threatened to ruin my life, then bought me an engagement ring and asked me to move in with him if I would take him back. Faked a car crash when I stopped answering him. At least he admitted to being obsessed and a narcissist but added "now that I know, I will change, so let's just get back together" 😅 Not to mention all the things he did while we were dating.
