Fightin bout baby name

My SO wants to name our son Waylon and at first I just brushed it off like yeah whatever and just prayed it would be a girl. Well it's a boy and I've tried and tried talking to him about the name bc I hate it. Literally everytime i think of my baby snd his name it makes me not even want him. My SO is the type you can even discuss changing names with bc it's his way or the highway about everything. Plus I wanted my first son to have my gpas middle name but he wont even budge about that and even if he did and it was Waylon Eugene I would still despise the name. Idk what to do bc I cant even be happy anymore I just wanna cry about it. It's really ruining this pregnancy for me and when I was pregnant with my daughter her dad was horrible to me and I'm not very close to her. Like I'm her favorite person an I love her but it's not the bond like other moms talk about and i firmly believe its bc her dad was so negative and didnt care about anything during my pregnancy and it's like a double whammy.
