JNSIL baby name

I feel like this situation I’m experiencing is something that would be on Reddit so here you go: I’ve been having issues with my sister in law since November. I went NC. (Previous encounters are in my last posts) I found out I was pregnant with a girl in November. I’m 20 weeks along now. I told SIL the name I had picked out before we started having issues. Her name will be Elayna because it has a lot of meaning to me. I wasn’t even 5 weeks along at this point. She was like my best friend at the time so I didn’t think anything of it. SIL found out she’s was pregnant in the middle of November. I did not announce I was having a girl and what her name would be until the middle of December in which this is when we were no contact already. We went no contact in the middle of November. I assume she already knew that we were having a girl as I was over the moon, happy, and crying about the results because I wanted my third to be a girl since I have two boys and this is my final pregnancy. So yesterday my younger SIL had informed me that JNSIL announced that she was pregnant with a girl. She’s naming her daughter Eliana. She claims to have the name picked first, that she had no idea we were naming our daughter Elayna, and that I needed to “shut my mouth and stop ranting to other people about this coincidence.” (This was texted to my husband) She said she was still deciding between this name and two other names and told my amazing SIL that she doesn’t like the other two names she had picked and will be sticking with Eliana. The names are not pronounced the same, but too similar for this “coincidence.” She is almost seven weeks behind me so it’s not like she will have the advantage of taking the name first unless she does something to cause herself to go into labor 2 months early. She wasn’t even pregnant when I had my daughter’s name picked. I really needed to rant about this..

Also, she’s been causing issues for me left and right. She’s turned her brother’s girlfriend against me even though she never liked her. She’s trying to turn my brother’s wife against me, but thankfully there’s nothing she can do or say to make that work because she absolutely loves me. She invited my husbands ex to her sons first birthday and wanted to have her sister send me a pic of them together. She told everyone I’m lying about who is the biological father of my first child, my husband’s stepson.
