my babydaddy hates my sons name what do i do

hey, i’m currently 33 weeks pregnant with my first son. he was not planned and his father is a man i have been on and off with since 2023.

from the day i found out i was pregnant my (at the time) boyfriend and i talked about getting an abortion as we are both quite young and as i said this was unexpected. i ended up having an ultrasound and as soon as i saw that little bean i knew i couldnt get rid of it, i was in love instantly.

after expressing to my boyfriend that i was thinking of keeping the baby i was called names, yelled at, being told i was dumb and i could never raise a baby at my age and then i was blocked.

a couple nights later when i was out with some friends i recieved a phone call from my housemate telling me not to come home anytime soon as (we will call him william) william was in my room trashing everything. i lived in a granny flat at the time so she was safe away from him.

this all happened when i was about 15 weeks pregnant and i didnt hear from him for a little while after that. i really thought i was gonna parent my child on my own which i was okay with but would idealy like my kid to have his father around if that makes sense. i had 1 boys name and 1 girls name picked out and was excited to try to have a positive pregnancy surrounded by friends and family. but around 20 weeks he reached out saying that he wanted to be involved and i said okay and tried to slowly build trust back with him.

although he claimed he wanted to do this, he has always given little comments suggesting he does not want this child or that his life is ruined. or there will be times ill express how over pregnancy i am (its been a rough time with all the symptoms) and he will say “well you couldve gotten rid of him” which upsets me.

i also call our child by his name but today he has said “can you stop calling him ____, we never agreeed on that name”. but i had this name picked when he had me blocked, when he was out every night doing whatever when i was really struggling with my mental health quite nervous for the future.

this doesnt have anything to do with how he would parent our kid but i also think its unfair that even after claiming he wants to be apart of our kids life he has yet to contribute anything, ive paid for every scan and baby item out of my own pocket with no help.

i just dont know what to do, i cant imagine my son having a different name it just feels perfect and i dont know if i should tell the controlling asshole to just F right off or if his name is still something that we both need to agree on
