Difficult Sister-in-law

So my sister-in-law has always been a bit dramatic and more so when it came time for me to pick my kids names. I have 3 and she has always had something negative to say about all of them. “That sounds like a stripper,” “That’s too white!” “I’ll call them sometime else.” Now Im pregnant with my 4th and we had thought it was a boy and agreed on a name we loved! She immediately started crying and having a panic attack and said it was the name of someone who had assaulted her. I apologized profusely and felt so bad! Turns out that it wasn’t that persons name and just happened to start with the same letter. 🤦🏻‍♀️ We’ve found out we are having our 3rd girl and she wants to seriously know why I dont want to give the baby her name or middle name. Really?
