Ex boyfriend tried to get me to have abortion but now wants say so in baby girl's name😕

Im currently 17 weeks pregnant and me and my ex boyfriend have been feuding back and forth my entire pregnancy. He begged me to get an abortion, said I was messing up his life, and he wanted me out of his life forever. However, now he thinks he should have some say so in naming our baby girl, who he didn't want in the first place!! I don't think he's going to abandon her but why does he think he should have any say so with her name when he didn't want her!!
