Should my baby daddy have a say in the name? Please read description

When I first found out I was pregnant with my last baby my "boyfriend" denied the baby for a few weeks before I finally told him since he didn't think it was his I was going to leave and do it alone. He had maybe 2 weeks that he claimed the baby but he was still accusing me of "doing him wrong" i ended up losing the baby at 10 weeks 3 days because of a car accident.

Well I'm pregnant again. And again he is claiming the baby is someone else's but also claiming that he isn't denying it. Every name I come up with for a boy he says he doesn't like it. He even told me "I will name my baby what I want and i don't want those names" so I asked about making the baby a junior and he said no because his name was too close to my friends nickname (his name Kyle hers Kai) and he openly admitted to being jealous of her because she's in the process of gender identity therapy and I have been trying to be there for her. (She lives on the other side of the country and we only chat like 1 or 2 times a week) he doesn't even want me to give the baby my papas middle name because my ex gave his baby my papas first name. All the names I asked him about for a boy name he has turned down. I told him if he didn't like the ones I come up with to tell me the ones he likes and he won't. There are times he tells me he can't name the baby because aparently the Baby isnt his. But then he says he should be the one to name it because I got to chose the baby's name with my ex. (My ex and I agreed before we even knew the sex of the baby the two names we wanted) should I just give up on having him help me on names?
