Did your SO help you pick the name for your baby?

I'm due in June and I still don't have a name that I love for my baby, and my bf is like 'did you pick a name yet?' but he doesn't help or give me suggestions, only sometimes he tells me really ugly names and laughs, I don't know if he thinks it's a game or what, maybe it's because it's a girl or maybe he's just being an ass. I would like for him to help me! Did your SO help you decide on a name or did you pick it on your own? I would love to hear opinions on this. Thanks! ^^
