Name changed as I do on a regular basis to remain anonymous.
My stbxh and I split last year and things haven't been good.
We unfortunately share a 7 year old child so still have to deal with all the shit he chucks my way - through our DC as we don't speak.
My DC mentioned her 'step Mum' this afternoon & I mentioned that this lady (who I've never met but I'm sure is very nice) is not her step Mum but Daddy's girlfriend.
He's been with his girlfriend for 8 months and he moved into her house after 5 months together.
Apparently, on the recent Mother's Day, he bought her a card with 'Step Mum' on it from his two DC (one not mine).
This lady doesn't have any children of her own but now seems to be picking up all the slack that my stbxh can't be arsed with - i.e. picking our DC up from school, providing his kids with a home.
Am I right to be pissed off that he is presenting my DC with a whole new family set up so soon after meeting his girlfriend? Feels like he's got his feet well under the table with her and taking things far too fast?
