Do you think im in the wrong?

My child father always hurt me physically especially when he drinks a lot. We don't live together anymore. So he ask me can I bring our son to him so he can spend time with him and I said no because I don't feel safe around him because he had put his hands on me before in front of our kid and he currently just one year old. If he never put his hands on me regardless the situation I wouldn't mind taking our son to see him. But I don't feel safe or comfortable because he tried to hurt me so many times I thought I almost died. He pull a knife on me. He push me when I was holding our son. He strangled me multiple times. I had enough so I left him. Since I said no now he call me a terrible mom.
