Bf gets mad every time we start talking baby names

Did anyone else’s bf act this way when picking a name for your baby? I feel like picking a name shouldn’t be this hard/complicated and definitely shouldn’t be something to get mad over or try to argue about. It’s not that deep. My bf and I will be having our baby in 2 weeks and still have not picked a full name yet because he has been SO picky. I had a whole list of names I liked (we’re having a girl btw) and he said no to every single one of them because he didn’t like them which whatever that’s fine I don’t expect him to agree on a name he doesn’t like, it should be something we both like right? I’ve respected his opinions on names but when it’s the other way around and it’s me who doesn’t like a name he suggests he gets PISSED and tells me I’m being unfair or that I’m not giving him a say blah blah blah. We FINALLY decided on a first name last week which was a name he picked and I didn’t really like it for the longest but he wouldn’t let it go and was not budging on it so i just agreed because I’m tired of looking for a name at this point. So he picked her first name, she’s also getting his last name and I really wanted her middle name to be my grandmothers name who recently passed a couple weeks ago but he said no because he doesn’t like it. He said he wants her middle name to be his moms middle name I said that’s fine because I like the name. Now today he text me and asked if we could add a second middle name because he also wants to use his aunts middle name as well which is Francis and I politely told him I don’t really like that name and don’t want to use it, shes already getting his moms middle name and if we’re going to add a second middle name id like to use one from my family. He got mad and started being petty and told me “whatever just let me know when YOU decide on what her names gonna be I’m done offering suggestions because you never let me have a say in it.” Like ??? He’s picked the WHOLE name but just because I didn’t wanna use the name Francis he’s mad at me right now and claiming he’s “not getting a say”🙃 I politely again told him I’m sorry and that I’ve respected his opinions so he should respect mine, I don’t expect him to agree on a name he doesn’t like for our child so why should I? I told him it’s not that big a deal it’s just a name and it’s definitely not something to get mad over that’s just stupid because we’re grown adults but he ignored me and hasn’t responded to my texts since. I feel like he’s being so childish and making it complicated. This is the only thing we’ve had an “issue” with the whole pregnancy and it’s starting to get on my nerves because we can’t talk about her name for more than 5-10 mins without him getting mad saying something petty and ending the conversation. I’m half tempted to just pick a whole different name by myself or just tell him to name her whatever he wants because I’m tired of the attitude he gets every time it gets brought up.😒 it’s not like I’m not telling him he has no say, I’m just asking that I also have a say. I should be allowed to not like a name and him not get upset over it like a child
