To want to rip ex's head off over his comment to 5yr old DD?

[iProcrastinate]

Ok, excuse my fuming-ness - I've had this recounted to me by an upset 5yr old!

ExH and his new GF took DD out for a day, he hasn't seen her in a few months and GF hadn't met DD before, but they wanted to take her for a day to a local attraction. DD was keen to go. This I have no problem with.

Apparently, at some point during the day DD had been playing and another person, innocently, said something along the lines of "you look like you're having a nice day out with mummy and daddy" - DD apparently said "that's not my mummy" and ExH stepped in and said to the person that it was, and later said to DD that his GF was "her other mummy", said that she should call her mummy because she was the same as her mummy.

DD was quiet when they dropped her off which I expected as she would be tired, but later recounted the story to me and got upset, I think she was confused by the whole thing.

My inner tiger mother wants to rip ExH's head, just for confusing and upsetting DD, but I wanted to check first whether I was being silly! AIBU?

Again, ex thinking of himself and maybe his girlfriend before his daughter and the mother of his daughter too for that matter.

Wow, I'd be so cross. Your poor daughter, and poor you. How selfish of your exH.

He really should not be saying those things to her, especially as this was the first time his GF had met your DD.

God! Not at all! Am going through a v similar thing at the moment - why I have literally just signed up. I really feel for you; it is beyond hurtful (and disrespectful) to suggest that anyone else ever is going to be a 'mummy' to your DD apart from you. Similarly, I bet you would never introduce your new bf as another 'daddy'. Wrong and confusing for DD, especially at that young age. What is the update on this and have you managed to have some constructive discussions?
