Ugh soooo freaking mad!!!!!!!!

So my boyfriend and I still can't come up with a name. I like the name brayden and I want to stick with it...he says no because his brothers name is Brandon and that's too close and maybey his brother would want that name for his kid someday....first off its not even that close I'm sooo fucking mad excuse my language...would I be wrong to still name him brayden??? He thinks he calls all shots but I'm carrying this baby and I'm annoyed ready to cry for someone to tell me no I can't name my child something upsets me soo bad when it's my baby
