Despite what he did to me, was I wrong for my choice of words?

Anonymous
I recently left someone who I cared and loved deeply but he treated me terribly, not all the time. That’s the side of him that I longed for and the side that made me stay and put up with the way he treated me for so long. He damaged me with abuse mentally, verbally and the physical was the worse. When I finally ended it for good and he continued to find ways to message me/contact me after I blocked him on every social media and changed my number, and me still hurt considering why I left, I told him that his mother should have chosen to give his father oral and maybe then he wouldn’t have been born. I also told him that the world would be better without him in it and called him belittling names that he usually called me and I haven’t heard from him since. I believe he deserved it. He has did and said so many things that it hurts to even go into detail about it because I’ll just break down but another part of me is saying maybe I shouldn’t have stooped to his level.
