Friend stole my baby name

My friend and I are both pregnant , I'm further along . When I found out I was pregnant I told her my baby names we're young for kids so doubted she'd ever take it . She ended up finding out she was pregnant & I found out I'm pregnant with a boy . She proceeded to tell me she was going to name her child if he was a boy the same name , then I told her I was naming my son that . She then said oh shit twins. Would this piss you off ? Because I am TOTALLY pissed off

Update :

It is not a common name , it's a very uncommon name in the Bible that me and my boyfriend learned about through a sermon that really spoke to us . She is not religious at all and makes it a competition about everything , she knows she took my name
