Mum allows 36 yo brother to live at home - AIBU?

My father died a few years ago, and my single older brother was given some inheritance for this, large enough for a deposit. He’s also lived at home for the past 7-8 years.

Meanwhile I am married and have a house with my husband. We bought our first house when I was 26, I am now 34. Mortgage, bills, CoL high. Trying for children.

I don’t get on with my brother, but I now feel resentful towards my mum for allowing him to live with her (and for this long) It doesn’t feel fair. My mum is constantly telling me that she’s short on money, but she also tells me that he does pay her something for staying there. I can’t help but feel it’s minimal, and he’s taking my mum for a ride. AIBU in that I think this is unfair? I also want to ask my mum how much and to help her advocate for herself but also don’t feel it’s my place. Don’t really know what I’m supposed to do here.

YABVU. And I find it bonkers that you're jealous and bitter. Why on earth would you be jealous of ANYone living with their mum at 36? I couldn't think of anything worse. Once I left home (at 20,) I never went back. And my DC left for uni at 18 and never came back. Most adults have no desire to live with their parents! Get a grip @RowsOfFlowers

Your mum is an adult with agency to make her decisions, it isn’t your role to advocate for her unless she wants you to. It’s also your mum’s choice, not your brother’s behaviour, that’s impacting your relationship.

My mum and brother have a similar relationship and I used to feel frustrated and want to intervene too. I came to realise relationships are a two way dynamic and, whilst my brother’s behaviour seems bad, my mum enables him. It’s not my problem to fix and it isn’t yours to fix either.

Is your Mum happy to have him living there with her, she may like the company and a bit of help with practical things around the house, or she may just not have the courage to ask him to move out..

We had a similar situation with my brother, he asked to move in with my dad for a few months temporarily when his marriage broke up, he never moved out. My dad was living quite happily on his own, he would regularly ask me if my brother was ever going to move out, in hindsight I think my dad wanted me to intervene, but I didn't and I regret not doing it.

My brother paid for nothing. I had bought the house for my dad so he had no mortgage, he was on a tiny pension, so I covered everything to do with the house, council tax, insurance, repairs, upgrades, etc. My brother lived there for almost 20 years until my dad died and never paid for anything or helped out around the house. . He did help out somewhat with my dad's care in his final years, but he really resented it and tried to convince us to put dad in a care home which he did not want. Said he couldn't cope with my dads illness, so we said, okay just move out as we intend to keep dad at home, as per his wishes.. But of course he never did move out. We hired full time carers for my dad at huge cost, even when my dad was bed bound, we had private carers come in so my brother didn't have to deal. He would be upstairs in his room on the weekend, and we had expensive carers sitting in the room with my dad because my brother didn't want to deal.

When my dad died, my brother expected to remain in the house, I offered to sell it to him at a cut price but he 'didn't want to buy it' just live there, i.e. I would continue to cover all costs associated with the house, he never even suggested paying a rent, he just wanted the status quo he had of no living expenses like when he lived off my dad. . I did sell the house and shared the proceeds of it equally with him and my other siblings, the same as if it was an inheritance from my dad's house.

My brother has never spoken to me or my other siblings since (who had nothing to do with the selling of the house) He and his daughter have badmouthed me to every relative under the sun, that I 'kicked him out' after 'all he did for our dad for 20 years'. Which is absolutely laughable, No one knows he lived off my poor dad for 20 years, he never even took my dad out for lunch once during the 20 years (17 of which my dad was in perfect health). My brother has a very well paid job, probably earning 10x my dad's small pension, and yet he still expected to live off my dad.

Sorry for the stream, your post just reawakened all those memories for me from 2 years ago.

Gosh, that’s a lot. I’m sorry for your experience. Just out of interest tho - seeing as tho you were paying for all the house costs, did it never cross your mind to enforce your brother covering some of the cost of that? That would’ve been an expectation I would set if I was paying for it all…

InWithPeaceOutWithStress · 15/06/2025 10:39

Sorry you’ve been getting such unhelpful replies, simply accusing you of jealousy. It sounds to me like your brother is exploiting your mother, rather than them having a mutually beneficial relationship.

We have similar in our family in that our younger sister is still living with our mum, she’s 25 and has never worked. Our mother is leaving the house to younger sister in her will because from her perspective it’s her house as she lives there, whereas myself and older sister have moved out. We weren’t given the option to stay, we were very much pushed out as young adults.

She is treating younger sister like a child, cooking and cleaning for her, taking her to the cinema at the weekends and so on. It feels really unfair that little sister is essentially gifted a free house for life, whilst we are saddled with mortgages having received no financial help at all. Little sister likely has autism but so do the rest of us in our family. My older sister has been diagnosed and I am on a waiting list. We were never given the option to avoid the world in this way.

The very irritating thing is that my mother would lean on me to help her out, for example driving her places, household maintenance, when I was younger I did lots of caring for younger sister. I know how incredibly resentful I will feel when I am inevitably caring for my mother as she gets older as she will naturally lean towards me for that rather than younger sister. I am heading that off at the pass by going low contact with them both now.

In your case I think you should start speaking more plainly to your mother. You don’t need to tell her what to do, but I can’t see an issue with asking the questions - how much is left on your mortgage? how much rent is brother paying you? Do you think that’s fair? Do you want him to live with you forever or do you expect him to move out? If the latter, have you told him this? Etc.

Funnyduck60 · 15/06/2025 10:38

So you would rather your mother live alone? Will your mum be likely helping with childcare in the future?

None of your business really is it. More and more people in their 30s are either still at home or have returned.

Im confused as to what is unfair. Do you also want to live with your mother but feel you can’t if your brother is there?

Seems to me that he is doing something you don’t want or need as you have your own family and house now.

Perhaps what you are really longing for is to be your mums little girl again and to be looked after. That’s fine - we all long for that especially when adulting is hard.

perhaps you imagine that this is what your brother has by virtue of living with her, and you are envious and jealous of it.

Possibly! I guess it just brings up a lot of worry and anxiety for the future with all the potential implications. And yes, maybe I do long for that. I never got as much support as him. It was always expected that I get on with it and I’ve developed quite a bit of perfectionism as a result as I feel I always have to be the super functioning adult without any problems

Secretroses · 15/06/2025 10:33

Are you upset because you feel your brother is getting more than his fair share of financial support from his mum than you are? You both got the same inheritance but your brother didn't use his to buy a house and now he is living largely off your mum's financial support while you are standing on your own two feet.

Wowwee1234 · 15/06/2025 10:32

It's not that unusual for one adult child to remain at home, especially nd. Your mum is probably very worried about what will happen to your brother after she dies. Clearly you are not going to step in as care giver. Don't talk about money with her - we can't take it with us, but do ask about this, she will probably open up more.

Boomer55 · 15/06/2025 10:27

Stand on your own two feet now, as you’ve had help already with an inheritance.

Who your mum has living with her is her business 🤷‍♀️

DontSpareTheTalons · 15/06/2025 10:24

I think you concern is understandable and I have been in that position many times with my parents. I also worried about them not making good decisions and they worried I did not make good decisions. We were constantly telling each other what to do and how to live and saying 'no' to each other would generally lead to resentment and arguing. It was a toxic and enmeshed mess of a relationship.

Ultimately, you can't rescue anyone and you can't make decisions for them. They need to do that on their own. Bailing people out also doesn't make the situation any better as you have been able to see with regards to your brother's situation.

What you can do, however, is say no. You don't have to listen about her money problems on repeat. You can refer her to your brother or suggest she hires a financial adviser and then change the conversation. If she needs help budgeting, you can offer to have a look, if that's what you want to do, and give advise, but that is where it ends. You can't live her life for her.

You can also say 'no' to many other things. You can say no to bailing her out and taking on her care and you can say no to shopping for others. You can also leave a situation that becomes intolerable. It's all up to you. You are only responsible for your own stuff and right now that is the life you have with your husband.

What an odd thing to be annoyed about. It’s none of your business. Perhaps your mum and brother are both happy with this arrangement. Sure your mum would have you too if you want to move back home.

I think she's annoyed because her mum keeps complaining to her that she doesn't have any money. If her mum didn't raise this every time they meet, OP wouldn't be worried about her.

Caligirl80 · 15/06/2025 10:20

Presumably she would let you life there too if you needed too?
Either way it's none of your business who she chooses to live with. Why are you so bitter? You have a house and family, be grateful and stop causing drama.

GreenOtter · 15/06/2025 10:19

Both my older siblings lived with my parents in their 20s and 30s, remaining single and also have chosen to be childfree. I feel my parents would have been ok had they not moved out (they did finally). My siblings visit my parents often enough that they may as well live there.

I moved out and married in my 20s and had a family. I am left out of many family discussions and decisions. After a bit of self-reflection, I found peace with it and am happy being on the outer. I tell myself that their relationship with each other is not my business. If and when they want to involve me, they have mouths and can ask. I have my own little family to worry about. My parents and siblings are the past and my little family is my current and future.

Insanityisnotastrategy · 15/06/2025 10:18

I think it's a stretch to suggest he's controlling or manipulating her, unless you have real evidence of that. Aside from your mum's money struggles, nothing you've said indicates to me she's unhappy with the situation. Maybe your brother is a difficult person, maybe he is just a real oddball who finds it very difficult to cope with a lot of things in life and therefore both he and your mum have made the decision to live together. It provides company for both of them.

Your mum is an independent adult, she doesn't require care at this point and can certainly make her own decisions, financially and otherwise. Again, nothing to indicate that she hasn't done all this with both eyes open. You've both had the same inheritance money so that's entirely irrelevant - whether it sits in an account or he spends it on rubbish is absolutely none of your business, frankly.

You can of course offer financial advice or just change the subject if you prefer, but don't expect her to necessarily take the advice you give. The chances are she knows you are resentful and will be wary of your ulterior motive with this type of thing, no parent wants to feel they're being 'handled'. Let her make her own bad decisions (if she is); if that means she's a bit short of cash and can't do all the lovely mum and daughter activities you would like - that's life. Situations are rarely perfect.

That same thing is happening with Grandad. My mum had to drive him across the country for operation recently - very serious op. My uncle barely does much around the house, and when I’d visited, they’d run out of basic items. I did a Morrisons shop for him.

Obviously, there is a pattern in your family of adult males remaining in the family home and providing little or no contribution either to the family finances or doing practical things to help their parent(s). Your mum has experienced this with her own brother and so this arrangement with her son seems fairly normal to her.

As other posters have said, you can offer to look at her finances to see if she is claiming everything she is entitled to but as she sounds unwilling to address the actual issues of him not contributing financially or helping with household tasks, there is only so much help you can provide. You can't afford to subsidise her and you are scared of confronting your brother.

In posts on the Elderly Parents board, I have seen posters recommending speaking to Age Concern when the OP is concerned about their elderly parent(s) being the victim of financial or emotional abuse by one of their adult children. I know that your mum isn't particularly elderly but as she is over 60, they may be able to give you some advice.

Surely it's her own business. Presumably she likes having someone else around after your father passed.

I agree. Stay out of it, not your business. If your mum is short of cash she would be even more so without your brother living there. If she is happy with him staying, don't worry about it. It's not that unusual and I doubt it will be forever.

BlueSkiesInJuly · 15/06/2025 10:05

My Db has schizophrenia and can be a bit of a twat at times. Sometimes he will turn up at DMs and help himself to food and ponce cigarettes. He also used to constantly borrow money. She can get annoyed and has moaned to me sometimes.

I've just replied that she needs to lay down boundaries and stop lending him money. I also model this behaviour. When she goes on moaning about him I just say I am not listening to this negativity. She generally stops and changes the subject. Maybe this is too blunt but I'm 45 and I just can't be arsed to have my head filled with moaning.

I do feel that it's not my problem, both my parents will try and put it on me, but his life is not my responsibility. I did help quite a lot before he turned 40 in working with the state on his behalf as I always felt that was the window of intervention. I've noticed he has also matured more recently (he is 48). DM has also got better at teaching him more independence skills like cleaning. Slightly different as DB has lived independently since he was 24.

In regards to finances, if your DM did sell the house and he couldn't live in it, can you be sure he wouldn't be a financial drain on her - if he can't cope independently? By having the house, it protects cash if she needed to pay for care in older age. I agree having a chat about wills and the future might help - it sounds like your DB will never live independently and she has to do what she thinks is best.

RowsOfFlowers · 15/06/2025 09:52

Yeah, that’s a good idea. So do I just ignore it then? It makes me feel like I’m repeating the history of the family, and engaging in the enabling 😕 I don’t know what the right thing to do is. When she visits, she seems happy enough, but I wonder if she herself is just … putting on a face. Oh well, I guess, I can only do what I can do.

Inevitably it would put a wall between you and your mum. That’s the cost of having boundaries, it inevitably distances you somewhat. But boundaries are to protect you - not to force change on other people. You can’t make your mum react differently to your brother and his situation, you can only tell her your side and - if necessary to protect your own well-being - withdraw from the situation.

The only chance you have to change the pattern is, if one of your children shows any sign of being ND or needing help in school etc, is to deal with it openly and determinedly and get them the help they need. You do it differently rather than following the pattern.
