I went through this last year and initially ignored my intuition. He's finally gone now, but he got a job with my ex - who I have a child with - the very next day. And yes, he applied for that job knowing my ex worked there.

I was able to avoid any physical violence from this guy, but it's only because I recognized his actions from previous relationships where I wasn't so fortunate. I think that things would have escalated if our time together hadn't ended so quickly.
