My husband hates all the boy names I pick

He likes Vivian for a girl and nothing I choose for a boy. I have a hunch it’s a boy and he won’t help. He also said he doesn’t even want to go over names until we know the sex. We have literally picked a name for all the other babies before we knew what we were having. I’m so annoyed. I have two girls Evelyn and Adaline. I have a boy named Ethan and I can’t think of anything he likes to go with Ethan.
