Adult step children still treated like kids

I am looking for feedback before I cause anymore problems.

My partner and I live together and have a newborn. He has 2 adult children (m20, f18) who live with us 50% of the time. Which is their choice to continue this until they are in a position to get their own place.

My partner and I have clashed a lot over the last year about how much ‘free rein’ his children get in our house. He feels as they are adults they should be allowed to come and go and do as they please. I agree to an extent, HOWEVER, I do not agree that they can have partners over every time they are in our house and staying over whenever they like.

We live in my house, which is a modest 3 bedroom, 1 bathroom, so space is tight. Also I am 9 weeks postpartum. I don’t want other people in the house all the time.
We had a massive fight about this and almost split up as I refused to back down. As I strongly feel my needs during this postpartum period is more important than teenager / young adults wants.

We reached an agreement with no sleep overs until baby is sleeping better and I feel ready and their partners can come over a couple of times a week for dinner but not every day they are here.

Neither of his children pay ‘digs’ . They had one chore each which again was a point on contention as the 18f had to be reminded every time or it wouldn’t get done. The chores were what you would expect of primary age children. I.e clean the bathroom once a week and turn the dishwasher on and empty it when done.
I have since refused to do their laundry so that is on them to do themselves now and if they don’t they will feel the impact of it. Not me.

Last night we got into it again. He offered his children the dinner left overs for lunch and was taking a portion for himself to work. I verbalised the observation that he never makes me up a portion of leftovers or even offers me some. I am lucky if I get the chance to use the bathroom in peace during the day sometimes as baby has colic so making a meal is usually out of the question, however he sorts himself out and his adult children with lunch for the next day, bearing in mind both his children were off work / college the next day. His response, “they’re my kids, I think about them. I don’t think about you”
Well I was pissed. I removed myself from the conversation but tried to speak later and he doubled down by saying that he “fathered them and will always think about them and that he is not my father”

I am still pissed. I am getting zero sleep as I do all the night feeds as he thinks his sleep can’t be disturbed because he is working. He now takes baby for a few hours in the morning at weekends to let me catch up on sleep but even this took an argument.

I haven’t ate a balance meal during the day since baby was born unless my mum has come up and made it for me and yet his adult children still trump me.

So…Am I being selfish or doI have a right to feel pissed off that not only do his adult children still come first but it is clear I am not even an equal?

Christ OP, throw the lot of them out! It’s your house!

You’ll need a room for the baby soon anyway, what’s the plan? The older one will have to go. I’d have said keep the younger one’s room until she finishes sixth form / college but from what you’ve said about your partner, I think you’d be better off without any of them.

Congratulations on your baby

NatureOverNightclubs · 14/03/2025 10:46

It's your house?! Throw his bags on the front lawn, change the locks and tell all three of them to FUCK OFF!!

twilightcafe · 14/03/2025 10:46

What a disrespectful bunch.
They all need to get out of your house.
Let dad put them up.
You concentrate on your baby.

maryberryslayers · 14/03/2025 10:48

I'd say no more overnights for the adults in your home and if he doesn't like it he can move out and house them himself.

Have you even been able to have a nursery for your baby given his 'children' are using the spare bedrooms in your home?

He's treating you like shit, it's not worth it.

Wingingitnancy · 14/03/2025 10:48

Kick them out, its your house. Tell him your thinking of your baby you gave birth to, not him. Your not their mother. :)

crackashark · 14/03/2025 10:49

It’s amazing how much having a baby sharpens your focus. I bet you’ve been putting up with all kinds of shit from them all for years. Don’t let your DD grow up seeing that, OP.

ForZanyAquaViewer · 14/03/2025 10:51

What is this man contributing to your life, exactly? As it’s not clear from your post.

Daisyvodka · 14/03/2025 10:53

Kick them out. I don't understand how he managed to convince you to have a child with him! Arsehole. 'I don't think about you' why do some men think it's normal to treat their partner worse than strangers!

Bananalanacake · 14/03/2025 11:08

It's your house but does he have any claims on it, does he pay towards bills, his adult DC should also be paying their way. Could they each cook a family meal once a week or is that too difficult for them.

How on earth have you come to be having 3 adults cocklodging with you in your house? What the actual fuck? You’re being taken for a ride.

beadystar · 14/03/2025 11:12

It's your house! Throw them out! Get supermarket delivery for you and baby.

CoffeeBeansGalore · 14/03/2025 11:13

Selfish lazy man spawned selfish lazy children. It's your house. Tell him he & his 2 "kids" are leaving.

KittenPause · 14/03/2025 11:17

Oh @manifestingit

you are being treated like shit by all of them

and sadly I agree that they all need fuck off out of your house

don’t put up with it all

it’s really not normal loving supportive relationship and household

legally you can just change the locks and that’s that

they can’t do anything about it

it’s as simple as that

change the locks 🔐

PyrannosaurusRex · 14/03/2025 11:17

You need your space, your sleep, and far more support, and I agree with you about the DSC needing to pull their weight, especially when it's your house, but pick your battles - (a) you can't give out to your DP about making food for his kids when in the next breath you say you don't get a meal unless your mum comes round and makes it for you, and (b) 18 isn't really an adult. It's a big child. But if big children aren't given active coaching into adult behaviour (eg, firm expectations about chore sharing, meal cooking, etc), they stay like that; there needs to be a united front on expectations from you and your DP and if you can't agree, then you need to make it very clear that this living arrangement won't work for you.

Where did the three of them live before?

SleeplessinPendle · 14/03/2025 11:18

He doesn't think about your newborn either by the sounds of it. Is this why his ex left him? Neglected them until she left him and requested child maintenance? Chuck them out.

KittenPause · 14/03/2025 11:18

CHANGE THE LOCKS

KittenPause · 14/03/2025 11:21

I feel anxious and stressed just reading about your awful situation

let alone living it

it’s not normal

change the locks

then sort out their belongings afterwards

Vroomfondleswaistcoat · 14/03/2025 11:22

Imagine you had to move in with another adult for a while. Then think of all the things that YOU would do to make their life easier while you lived there (particularly if you're not paying them rent). That is what your SC should be doing, and would have to if they houseshared/moved in with friends.

BansheeOfTheSouth · 14/03/2025 11:27

Are you married? I know you say partner so assuming you are not.

These young adults do not get the choice to stay in your house until they decide. You decide. You have up to 4 freeloaders and not one of them cares about you or your newborn baby.

Tell your partner, they are being given a month's notice. They don't pay anything or contribute. They have zero rights in your house. If he doesn't like it, he can go too.

Can you financially survive without partner? He will need to pay maintenance for your child. Understandably you might not be in the best position on maternity leave.

caringcarer · 14/03/2025 11:30

Not only does he disrespect you he allows and his DC to disrespect you too. Also if he is such a wonderful father why can't he step up with his baby too? I'd tell him things change dramatically or he can leave and take older DC with him and he can send you maintenance for his baby.

TomatoSandwiches · 14/03/2025 11:30

Get rid of them all, he literally said he doesn't think about you at all, well you've birthed his third baby so he should be thinking about you and supporting you but is instead focusing on capable adult children instead.

Nope, he and they need to fuck off, I bet it will be more peaceful for you with them gone.

Thatsenoughadulting · 14/03/2025 11:34

Fucking wow! He's going to get learn the hard way why your spouse should always come first when his kids leave and he's a lonely old man because you've had enough of his shit. If he can be so uncaring when you're at your most vulnerable this really isn't going to get better. Get the lot of them out of your house!

My 18yo SS lives with other us full-time and has always done his own washing, helped with chores each day and pays his way. There's been a few times he's had the "if you don't like the rules here you can always leave" lecture from my DH. My DHs kids are his world but so am I and he'd never put their wants ahead of mine. We're not even talking about little kids here but adults! It's ridiculous.

Rightsraptor · 14/03/2025 11:38

You've had three adults move into your house: that in itself is incredibly stressful but adding a new baby and a so-called partner who's made it plain you're at the bottom of his list of priorities - just incredible.

Boot all three out. Now.

theressomanytinafeysicouldbe · 14/03/2025 11:39

Christ my children stopped staying at their dads when they were 13/14. See him every now and again or if they want something but maintain contact by phone.

I feel its unfair 50% of the time for adult children, do they both stay at the same time or alternative nights or what - not sure how the 3 bedrooms work.

I had to set boundaries with my DC's girlfriends. It got to a point they were staying 5/6 nights a week (2 older DCs girlfriends). We sat them down and explained our house is small, me and dad need to be able to relax and not have people coming ang going all the time, and explained with them other DC and us there were 7 people in the house and once and youngest DC is coming up 16 and when he eventually gets a girlfriend, there will 8 of us in what was a 3 bed semi (got garage converted so now 4).

We have put a limit on 3 nights a week as long as they also spend time at their respective partners home some night a week to make it fair - we do not feed them, if they want to be in an adult relationship, they work so they can buy/cook their own meals when their partners stay. And when they get up to go to work or whatever their partner leaves with them, they don't stay in the house if DC's are not here.

It kind of works, best we are going to get I think.

Could you set some boundaries like this? so say they stay with you 3/4 nights a week, their partner can only stay 1/2 nights a week, and when they do they provide and cook their own meals?
