LONG STORY:
I've been so excited about LO birthday that I have had a theme and ideas picked out since two months ago...Mickey!! (I know, how original, right?). I took him to Disneyland and we had such a great time. We also got him a Mickey hat with his name, so a Mickey birthday seemed appropriate.

I made the mistake of sharing my ideas and excitement with my husband's niece, we'll call her "A". A few weeks ago I got word from "A" that another one of my husband's nieces, we'll call her "B", whose LO turns one a month before my LO does, chose to go with a Minnie theme. WTF!
If I believed it to just be a coincidence, I wouldn't be as bothered but this "B"-otch is known to pull this kind of crap with people. She's never liked me, always tries to one up me, is very jealous and competitive and is the kind of mom to ask about the way you do things only to criticize and offer her own opinion. She's younger than me by three years, but emotionally she's about 12.
My husbands family will be at both parties and will most likely side-eye me if I throw a Mickey party after she does a Minnie one.
I know, I know, it's so petty but I really want to sock her in the face right now. I also don't trust niece "A" anymore. I feel like she told "B" and "B" is chose Minnie to spite me. I've learned my lesson.
What would you do? Confront her, let it go, change the theme, keep the theme?
Sorry for the rant.

FTM to my sweetpea Miss D.
I understand being frustrated and annoyed though, it does suck but I'm sure no one will bat an eye and if they do then that's just ridiculous.
