Baby name dilemma

So me and my ex boyfriend relationship went down hill pretty much after I told him I was pregnant! Yeah, after 5 years I thought he qeinuenly cared and loved me until I popped up pregnant smh! Anyways, so after months of us going back and forth arguing with him trying to get me to have a abortion he finally stopped trying to force abortion on me after he figured that my mine was made up. However, he still has been unpleasant to deal with due to his comments saying things like:I trapped him, he didnt want a baby, He wants a DNA test, I'm messing up his life etc. Since he had been such a asshole I picked a name for her prior to her birth, but now that shes here (born 9/12/18) and he figures he should have some say so in what her name is! He's a good dad to his other children so I dont doubt he is going to be one to her as well. A small part of me is saying give him some say so. However, I really dont want to budge either and just would rather keep her name as it is. Opinions?
