Baby name

My Ex SO had his heart set on a certain name, but he expected to give the baby a name he chose and his middle and last name, if it is a boy. While we were TTC we had discussed doing it. but since we haven't been together and he constantly ignores me, never asks about the baby appts or how anything is going, but still demands that I keep the name the one he wanted. It seems like he just wants his legacy to go on could care less about what's going on, I have sent him ultrasound pics and he never said a word. I am prepared to do it alone, and I am not kicking him out of the baby's life I have told him he is always welcome to see the baby as much or as little as he wants. But, i have changed my mind since I never cared for the name. I was going to do it to make him happy. Am I wrong for not caring about his opinion anymore?
