I'm genuinely not sure if I'm being unreasonable and would really appreciate opinions.
My parents are divorced and did so when i was 16, it was a very tumultuous time and although they are amicable, they have been very self centred both before and after the divorce. They both parented with what i heard once described as 'benign neglect' but also hitting and growing up i felt quite isolated from my parents.
Post divorce my mother has had 4-5 relationships and each time she 'forces' her partner on myself and siblings. She always introduces them very quickly and just moved too fast with our relationship with them. They then don't last and now i have her ex in my wedding photos she insisted on him being in, etc.
I didn't mind too much until i had kids. I have 3 DC (oldest is 4 yo) and in that time she has dated and broken up with a partner and now has another partner that has met my kids, we have been on an international holiday with them both, she really forces him on us and i really dislike it.
Her partner doesn't see his children because of a messy divorce, perhaps that's why she tries to force his presence on us. It's just annoying because sometimes i just want to see my mum or talk to her about things i can't in front of him (i had a miscarriage and literally couldn't find a time to talk because he's always around, even when i zoom call).
On the other hand my dad has had 1 partner for the past 7 years and he doesn't bring her on holiday with us but I've met her kids, I'll have dinner at her house occasionally and i invite her to my place as well but it's not expected that she'll always visit with him or be at dinner, etc.
AIBU to tell my mum that although her partner means a lot to her, he is a peripheral person in my life and I would like to see less of him.
