I agree with Hello.
It’s why I’ve personally never bought into this idea of a SM that should been seen and not heard. I find it totally infantilising and diminishing of my “place” in my own home and dismissive of my parenting choices towards my own child.
If DSD’s mother doesn’t care about table manners that’s her choice - but I do and I’m not going sit and watch a meal I’ve shopped for and prepared being shovelled down with a spoon and fingers or with cutlery held incorrectly whilst “fighting” with my DS why he’s not allowed to do the same. Equally with other things such as rooms being tidy, beds made etc. Same “house rules” for everyone and I’m going to pull anyone up on it if they are not followed.
Weekends are not going to be dominated by what DSD wants to do to keep her happy every possible minute she’s here, she doesn’t get control of the TV at all times or choose exclusively what film we see at the pictures. A planned day out isn’t cancelled because she decides she doesn’t want to go. In short, she’s treated in exactly the same way DS is.
We are a family and we all have a voice - and that includes me - when it comes to how the household functions.
That said I don’t get involved in what I would call “big lifestyle” decisions like where DSD goes to school, her academic choices, if she gets a piercing etc as I do think there are decisions to be made by her parents and her. I’ll give an opinion if asked but that’s it.
I often feel so many blended families don’t work because step parents are often totally isolated and marginalised in their own home. Expected to be supportive, yet have no say whatsoever in how the overall family dynamic functions and criticised for pointing out that it’s failing.
It’s impossible for anyone to stay invested in such a set up. It’s not a family, it’s dictatorship where the needs of a sub set of the family are prioritised above the needs of everyone else - including half siblings.
FWIW I have a great relationship with DSD and mine and DH’s relationship with her mother is also positive. I think that is in part due to the fact that DSD (aside from knowing I love her and would thrown myself under a bus to protect her) respects me and knows I won’t pussy foot around her (no wonder so many step children have no respect for an adult that can’t even enforce something like basic manners saying please/thank you because they aren’t allowed to do “discipline” in the home). I’m fortunate that DH has also agreed this is the right approach.
OP I really think you need to sit down with your DH. He’s fundamentally the problem here.
I think he’s failed to understand that you having a child now has utterly changed the family dynamic. He’s no longer the “only” parent in the house and his (and his ex’s) rules are not the only ones that matter any more. It’s not fair for you to have to “inherit” their parenting styles (especially when you don’t agree with them) wrt to your child.
I’d suggest you maybe consider the set up that’s worked for us - we have “house rules” that everyone is expected to abide by. Basic things around good manners, tidy rooms, making beds, respecting people’s property and privacy, sharing decisions on where to go/what to do at a weekend etc and doing that together.
If he doesn’t want to agree to that then personally I probably would walk away. I couldn’t standby and watch myself/views/esteem being constantly diminished and parenting values discarded.
for you
