Thinking it’s weird that his 18 year old will have the master room

Op you sound appallingly greedy.

I hope you grow up a little.

OP don’t sell your home, wait a while just incase.

Had a partner come into my home and said that, I would be telling them to not bother unpacking their bags, as they wouldn’t be staying long!

It's weirder that you think you can move into his home and kick his child out of her bedroom!

I'd find a man without this odd arrangement

I'm not so sure that the OP wants to let go of this allegedly very wealthy man.

I think it's nice he gave her the better room and agree it sounds like it makes sense. She actually uses it as a living space whereas he has the rest of the house. I think you must want to pick a fight with this girl.

And they didn't get the support they wanted and only replied to those who supported her view, failed to answer anyone who questioned her.

Waiting for this to appear on that certain website or in Take a Break.

YABU to expect to change the status quo just because you're moving in.

Are you planning on letting it go now he's told you that or will you be a dripping tap to her, constantly letting her know you're unhappy she's got the 'better' room and you deserve it more?

Mind your own business.

Why does it seem odd to you? Two adults aren't sharing a smaller room. They are sharing a house and sleep in a room. You have the use of the office, his daughter doesn't. It makes perfect sense for her to have a bigger room where she both sleeps and studies while two of you have the use of the rest of the house.
My grandparents have a 4 bed flat. The master bedroom was always my mums since she was 4 years old. They sleep in the second biggest bedroom and have a use of the adjacent office with plenty of storage space.

I'm glad you can see it!
I can't stand troll posts. We have enough stuff happening in the world without reading mumsnet stuff outside of here.

Also it opens up wounds for the posters who knew how it felt to be treated differently by step parents. I felt sorry for the genuine posters who had replied.

It doesn't matter if you think her having the master is weird. That decision has been made and it is HER room. (And I don't think it's that's weird - decision based on needs / uses of rooms.)

It's a bit shitty that you think it's OK to put her out of her room because you feel more entitled to it.

And it's not like you're being put in a box room. Your room will probably be vastly superior to most people's master.

If I were you I'd say nothing about it lest I sound insensitive and grabby.

Why are you selling your home ?
surely you would want to rent it out or buy another.

what about your future ?
where will you live if you split up ?

Talk about biting the hand that feeds…

No it’s not weird that the daughter has the master, not weird at all. Young girl, lots of clothes, likes space. Dad still has his own en-suite. It’s interesting you are moving in and thinking it’s weird and daughter should move rooms, it’s her home and was before you.

It sounds worryingly like you want to assert authority over his daughter.
This is his house, and her home. You have no rights here, but you are going to alienate yourself from her if you don’t act with more care.
My 18 year old DS has the largest bedroom too. At their age it’s not just a room, it’s a social space where they host their friends. You’re being very unreasonable here op.

No, it is not HER home, it is HIS home. She is a young woman of 18 not a six year old. TWO adults need more room than an 18 yo girl, who is in a transition to independence elsewhere (her own place hopefully). This man's reaction says it all: he expects his girlfriend of FOUR years (!) to play second fiddle to an 18 year old.

You cant move a girlfriend in and remove the daughter from her bedroom

Im glad he said no. Who the fuck are you to dictate what happema with his daughter? You need to think about appropriate boundaries

No, it's the daughter's home. She lives with her dad. A girlfriend moving in doesn't take precedence.

Aaaah, the Take a Break stuff makes sense.

Op was coming across as fantastcally ridiculous.

Silly me, I fell for it. Well, that's good news. I was feeling so sorry for some poor 18 year old who was about to have a tonedeaf bombshell dropped on her. 😁

1. why are you selling your house? You should keep it and rent it out unless you are getting married you will leave yourself in a vulnerable position

2. YABU to try and oust her from a room that she and her DF have agreed makes sense. You are moving into a house he owns.

3. read 1) again

What a load of bollocks.

It is her home.
It's more her home than OPs home.
oP has ZERO claim on that house, none, nothing at all.

Daughter trumps girlfriend.
Whether they're 5, 18 or 35.
Your kid is your kid forever, partners are a dime a dozen.

His ex was before her, too but that doesn't mean she should play second fiddle to anyone if she is "it" in HIS heart. Good grief there is a boundary that needs to be laid down: we are the adults and you are not, therefore this is the plan: we need more room than you. I cannot IMAGINE having my clothes in separate closets, either. Ridiculous.

Your entitlement would be concerning to me. You’re going from a £250k house to a £2.5m and you’re complaining.

I sense trouble ahead.

Just because you're moving in with this guy goes not mean you are automatically entitled to have the largest bedroom with ensuite and walk in wardrobe. The daughter was here first. You will always take second place.

If you're not careful you will be 'last in, first out'.

Absolutely 2 adults need more room.
That's why they also the lounge, dining room, study and 4th bedroom to use as they wish.

Meantime, the 18 year old only has her bedroom.

18 year olds are not generally in transition to anywhere these days due to cost of independent living; i would imagine she might be living with her father for quite a few more years to come.
