I didn't say you'd want to do it.
I said I bet you wouldn't say it to your daughter.
Some mothers don't want to meet the potential stepmother, but a lot do. If your daughter said to you she really wanted to meet the woman around her kids would you be so dismissive telling her it wasn't her place, I very much doubt that!!!
For the record I have felt zero need to meet my exes latest girlfriend seeing as my ex is barely around their dad anyway and they're older now. And even when my youngest wasn't talking to her dad for months and months and the girlfriend asked her if she wanted to go for something to eat I said that was fine without needing to meet her, but that's because we're at a different stage of life now and I also know that the girlfriend is never going to actually be doing any parenting or step-parenting seeing as they barely see their dad.
I said earlier on the thread that me and my ex did have an agreement to meet new partners first, and he introduced someone to the kids after sleeping with her twice and moving in, but then told me he'd still expect to meet anyone I introduced so he could grill him because it's different when it's a man 😆
There was a couple off issues very early on where my youngest told me the girlfriend put her up on social media. I said to my ex it wasn't appropriate and then that didn't happen again as far as I know.
I ended up not meeting the girlfriend then for a good while after that, my ex wanted us to meet loads of times because he said we'd get on and be friends 😂 my ex had her outside in the car one day and asked did I want to go and say hello then and get it out of the way or did I want to wait until a different day when I was dressed or more done up 😂I was like "no, why would I care what I look like?"...so I went out and said hello and broke the ice and we actually became really good friends after also 😂
So I've never been in the position myself where I felt like I needed to insist on meeting, however I can empathise completely with mothers who do feel like they need to meet the woman who is potentially going to be the stepmother to their kids, and I wouldn't tell any mother it wasn't her place based on my experiences.
I think it must be so sad, upsetting and emotional for some mothers, especially those with toddlers and small kids to know that another mother could be potentially stepping into her role doing bedtime stories, cleaning cuts etc. and a little bit of compassion and understanding can go a long long way. Treating her like an irrelevant nobody is bound to cause hostility and is not in the kids best interests!
