AIBU to question what my fiancé expects of me as a stepmum?

Hi,

i’m engaged to a man who has a child (aged 7). I’ve be with my fiancé for 4 years, and in his child’s life for 3 years (we waited to introduce me to his child as they’d had a lot of disruption in their short lives).

this is my first time in a relationship with someone who has a child. From the beginning I really tried my best to be kind, loving and caring towards my stepchild. I feel like I am a good stepparent and that stepchild likes me, maybe even loves me. I love my stepchild, I love it when they’re here, love chatting and playing with them (as long as it’s not with figures haha), love our family days out.

I don’t want to assume a mother role as my friend has a stepmum who did this and she resented her (still does) that she tried to be that to her. There’s a few things I don’t do, bath times and school stuff. I feel that’s overstepping the mark

fiance has recently said I need to be “doing more” and that “you’re a parent now, so you need to think of these things, you need to do XYZ”. He’s very critical if i have an appointment or seeing a friend on the days stepchild is at home with us.

he also said that I should love stepchild as my own. I don’t know what this means - I’ve never had a child, I don’t understand what that love is. And then I got thinking, I don’t “miss” stepchild when they’re not here, I don’t feel an urge to rush home to be with them. I’d do anything for them, but I don’t feel intense love.

fiance has said that I am very privileged to be a stepmum, and that I should be over the moon. He also said that he doesn’t me separately to being stepmum, for example, he said im a family member, and so it doesn’t matter if im his partner or stepmum. he said when stepchild is here, we can still function like a couple but include them in dates, eg. Date night with us all.

Im really confused. Should I be doing more? Am I a terrible stepparent?

Wonder if he'll start the 'woe is me' once he realises you've left, or accuse you of abandoning his DD, which in turn is where you can remind him that as you're not married she isn't infact your DSD at all.

I'd also do as suggested if you can and pack all of your belongings so you've no need to go back.

Hopefully being away will give you some thinking time in that he really isn't the man you want, or should be wasting spending your future with.

Kokonimater · 10/05/2026 20:33

He’s narcissistic and using coercive control. Please be aware when he realises you’ve gone that he will try every trick in the book to get you back. he will make promises, he will cry, he will beg. He will be very persuasive please look after yourself. And please see through all the promises he will make.

Because he’s shown you who he really is take lots of care of yourself.

You’ve dodged a bullet here @Theworldonfire thank goodness you are realising this now and not post-wedding xx

This.

Good luck @Theworldonfire , you sound lovely, which is how he hooked you in the first place. Stay strong, the kindest thing for your DSD is a clean break and it’s the kindest thing for you, too. As pp said, he will throw everything from flattery to abuse at you to make you change your mind and come back to be his maid and nanny once again. Stay strong, you’ll be amazed at how good it feels to not be with a manipulator.

Just thought I’d update.

He’s escalated over the weekend and shown me in no uncertain terms that I’m an on duty babysitter. I had a migraine yesterday and had a nap around 1pm. He slept on the couch last night and said he’s “sick of all the rest I get whilst he has to get on with it”.

Today I was meant to visit my elderly mum. He said “oh so you’re “sick” yesterday but you have enough energy to spend time with your mother today and leave me and dsd again, having spent no time with us yesterday?”

for context, I spent all day with them yesterday, bar the 1 hour nap.

i didn’t end up going to my mums because i just knew the atmosphere I’d come back to. Cue him saying “why’ve you cancelled going to your mums?” All shocked.

I have told my mum everything (there’s more than just what’s on this thread, but I don’t have the energy to type it). I am going to work as normal tomorrow and then driving straight to hers where I will stay for however long I need/want. She told me not to let him know I’m going.

JFC his behaviour and attitude are absolutely shocking! His sense of entitlement is off the charts and he is incredibly rude as well.

I'm so glad that your mum is supportive and that you will be staying with her for a while.

I predict that he will have a massive tantrum and he might make some promises that he has no intention of keeping to try and win you back. Stay strong!

I’ve read every post, I appreciate all the replies. I’m really overwhelmed at the amount of responses and that they all say the same thing.

I do feel manipulated. I’m told that if he was a stepdad he’d do xyz.

He pushed back massively a couple of months ago when I was too unwell to get out of bed for around 4 weeks. He said he was desperate for adult connection, that he was isolated doing wake ups and spending his day with his child alone. If I don’t get up as soon as stepchild arrives I’m ruining family time. If I have plans on the day they’re here I’m ruining family time.

When they’re not here, he floats around and does what he likes, says if I want time together that I need “cradling”.

Honestly sick to my stomach right now because it’s all real. I’ve never spoken this out loud. I feel trapped and like he’s testing me at every turn.

Op. This isn't a healthy relationship. But I think you know that. I am so sorry..its going to get worse until you don't know which is right or left.

pinkyredrose · 10/05/2026 20:54

Great update Op! Hope you're feeling ok.

NameChangeAgain48 · 10/05/2026 20:54

He resents you. He resents his DC. he thinks your purpose is to serve him and his child. I'm glad your leaving. His a shit dad and a shit partner. You deserve better.

Whiteheadhouse · 10/05/2026 21:03

You do realise he is controlling, manipulative and coercive? I absolutely believe he is capable of serious abuse of you.
Gather anything sentimental, paperwork, jewellery, passport etc., and bring them with you.
He is quite capable of destroying stuff or losing your stuff out of spite.
Take anything of real value.
Do not tell him anything.
Can you leave after him?
Email work that you will be late and gather a decent bag of clothes.This is a bad man who sees you as a skivvy. He is a shit father and definitely not a man to ever have a child with.
He will definitely try and get you back, be ready for that. He doesn't like his child and needs a woman, any woman to be his skivvy aupair.
Such a narrow escape.

ScrollingLeaves · 10/05/2026 21:04

If I were your dsc child I would want to like and trust you, and to enjoy being with you, but I would not want you pretending to be my mother, or my ‘parent’. (Unless their mother has died or run off, and even then I’d want boundaries.)

ScrollingLeaves · 10/05/2026 21:13

I am going to work as normal tomorrow and then driving straight to hers where I will stay for however long I need/want.……..

MWhat ever you do don’t go back.

That man shoukd not have had 50:50 either. He resents his child, and he is horrible.

Thisisusie · 10/05/2026 21:20

OP I’ve said it upthread but I’ll say it again - this man doesn’t care about you at all. He has no compassion or consideration for you and he is jealous that you’re child-free.

He’s trying to make his responsibility, your burden and it’s not. So please run and stay at your mums until you’re able to get your own place.

And also look into therapy to gain understanding on why you’ve tolerated this so you can be aware of the red flags next time.

ChavsAreReal · 10/05/2026 21:23

Take your passport/laptop/photo album with you tomorrow. Just in case...

You sound brave. He sounds like a lazy useless good for nothing. Good luck tomorrow.

AnneLovesGilbert · 10/05/2026 21:25

Sounds like your mum has the measure of him and really well done for being honest with her, I know how hard it is to admit your relationship isn’t what you’d want it to be, it’s a massive step and so is going to hers from work.

When I left my ex I was too scared to tell him my plan so I said I was going to stay with my sister for a few days to help her with something and never went back. I called him a week later to say I was filing for divorce, he went mental and insisted we meet where he screamed and shouted at me and threatened me and then he stormed off. Like that was going to change my mind 😂🤦‍♀️ By then I’d got some space in my head from not having been in the same house with him and just powered on sorting practicalities. You’re being very brave and you’ve got us here to support you as and when you need it.

Yes...this! Pretend you're going to work but call in work that you need a day off urgently.

Then clear everything out to your Mums! He won't expect it and you'll be safe.

Agree with this. Good luck, OP. Wishing you well.

Lmnop22 · 10/05/2026 22:01

I’m so glad you’re leaving. Even if you were DSD’s parent, imagine getting stick for needing a nap due to a migraine and visiting your mum at the weekend…! And you’re not even the parent and you’re getting more heat and pressure to parent than her own mother would get

Chickadeeinme · 10/05/2026 22:12

Make sure you take your passport and any bank stuff of yours with you. Most other things are easily replaceable.

GingerdeadMan · 10/05/2026 23:06

So glad you are leaving him, he's treated you like shit and it would only get worse.

Reminds me of my ex husband. I left him and never looked back, and the same will be true for you xxx

I'm so glad you talked to your mum and are going there to stay. He's really shown his true colours. What a hideous specimen. Thanks for the update and wishing you all the best 💐

PS what a fkn shit parent he is!!

Your mum sounds ace. Glad to know you are being supported. He is an arse and I feel sorry for his poor kid. I don’t know much about what causes migraines but not having the stress of living him certainly won’t do you any harm.

DrinkFeckArseBrick · 10/05/2026 23:40

Good luck OP, I know it's not easy but I'm sure you're doing the right thing x

Studyunder · 10/05/2026 23:55

Don’t ever doubt yourself. You are the most important part of your life! Take anything that’s dear to you/important. Sending you strength

99bottlesofkombucha · 11/05/2026 00:38

Thank goodness you’ve seen what he’s really like! He doesn’t love you op, there’s no genuine caring for you. I was horrified by the ‘I was sick for 4 weeks’ story.
