What should I do? 😩😩

So I’m at the term of trying to pick boy and girl names to choose from but when I do, my SO doesn’t like it. I tell him to help me on the options, but he wont and doesn’t take it serious.

I picked over 20 names and he disliked and made fun of EVERY. SINGLE. ONE.

Then I say “well what kind of names do you like”

And he just laughs and names off jokes.

WHAT DO I DO? Pick the name by myself and him get mad or not name him/her at all because he won’t take it serious? 😩😩
