Toxic? how to leave? ?

I am engaged to a man I've known my entire life. I moved away from home years back started a new life, had a child things went south so I packed up and loved back home. When I moved back me and my present fiance reconnected. Now we have a one yr old son. The second I found out I was pregnant everything changed. I was his property and he wants to control everything I do. He's my best friend, first boyfriend, date to every homecoming 5 consecutive yrs. I love him but can't live like this anymore. He hates the father of my 4 yr old and causes so many problems. He can't even drive with me to meet her dad on the weekends. He hit me in the face in february with a beer. 13 stitches later I still stayed. Last saturday was the 1st time I've been out with friends in 2 yrs. He called my phone a literal 200 times. Threw all my stuff outside and when I tried to leave he grabbed my leg and told me I could never leave him. I know its a toxicrelationship and he doesn't even think he had a problem. I've begged him to go to counseling and he refuses. Is there anybody that has been thru anything like this, id really appreciate any advice, no lecture please. I've heard it all.
