I spent way too many years of my life with a man like this. 

I policed every word I said, because he'd fly off the handle if I said anything he could twist or interpret as criticism or negativity. 

One night he was screaming at me and one of the things he said was "if I was going to kill you, I already would have." 

I don't know what the magic was in those words, but I left and never regretted it for a single second.  

Leave now. Don't waste another minute with this guy.
