He got someone else pregnant and now he's begging me to take him back what do I do?

A year ago i had found out my boyfriend allegedly got a woman pregnant. He blocked her and we moved on with our own lives. Now, a year later, its another woman saying she's pregnant by him. Which he's saying he's not the daddy. He said that last year. Im just over it. He's been calling me threatening me because i told him i was done with him. What do i do? He said if i don't take him back he's going to do something to my daughter.. and THATS why im finally done. I posted a video of me bending over in my underwear so that he knows im a free agent.
