My SO wants to name the baby.......

I wanted to agree on a name mutually. But that’s not going to happen. He says he should name the baby. And the name he keeps bringing up is

“Zaythoven” like Beethoven......

I do not like that name at all.

So now he’s ignoring me because I told him I don’t like the name and that I wish we’d look at names and decide together.

EDIT: I definitely will not be giving the child that name. Regardless of how upset he is.

He seems pretty serious about that name.. he’s been saying it for WEEKS... plus he said he will go have kids elsewhere and name them himself since I’m being “selfish”
