Best friend stole my baby name

So would this bother you and what would you do???

One of my best friends is currently 12 weeks pregnant, last night we was taking about what names she likes and the first boys name she said is one that I told her was on my list a few weeks ago (the name is NOT common and one that I actually made up myself!)

When she said it I just said “oh that’s on my list!” now I think back I wish I had joked or something and said don’t steal my name 😂 but I think I was just shocked that she even said it tbh as like I said I thought up this name myself.

Me and my partner have been going through IVF for the past 18 months so she knows I’ve had a list going for god knows how long.

The more I think about it the more I’m getting more and more PISSED 😩 kinda hoping she has a girl now lol!

Would you approach it and how? Be HONEST

I am not pregnant yet btw!
