Is this too harsh?

So, a little background information before I ask this question:

I know this girl from high school. She’s only 20 and has a two year old girl with one of my best friends from HS. They didn’t last which is fine, it happens. But she just started dating this guy in October who also had a child from a previous relationship and the entire evolution of their life over social media genuinely makes my skin crawl.

They’ve been dating for three months and she makes his son call her mom. Her daughter calls him daddy. They’re talking about getting tattoos with each other’s kids’ names, trying for “their own” baby etc., etc.

Her baby daddy and I have been friends since 7th grade and he’s so irritated that she feels like her boyfriend of NO time at all can tell him whether he can or can’t spend Christmas with his kid. I’m their mutual friend but when she shared this on Facebook, I lost my shit a little. I tried to stay composed as possible and I was just wanting to check with other WOMEN to know if this message may have come across muddy or judgmental.

I understand that it’s none of my business and I don’t want everyone on this poll just telling me it was none of my business. Let me know what you think!
