Jodie, that guy is scary and nuts. Run and don't look back! Go no contact and get yourself a therapist, you need a safe place to talk about it all. This place is great but face-to-face with a professional could be a lifesaver. Good you called the cops! Better that he dumped you!! You dodged a huge and awful bullet.
I was dumped by my "soul mate" and lived not only to tell about it but to be ECSTATIC and hugely grateful about it. Not at the time of course. But in the long run.
