Just need to get this out. It’s long, messy, and I don’t even know what I’m asking really

My younger brother (17 end of Aug) moved in with me back in May after my mum basically couldn’t cope anymore. I’m 13 years older than him and pretty much helped raise him. Changed nappies, fed him, school runs, everything. It’s always been me stepping in when mum couldn’t. She’s always had MH stuff – depression, anxiety, agoraphobia – but never got help. She’s not well and hasn’t been for years but just refuses support.

Our dad cheated when my brother was a toddler – around 2 – and they split. Dad actually stayed involved for a long time after, regular contact, weekends, school things. But then moved back to Germany when my brother was around 10/11. That’s when things started to unravel. My brother doesn’t remember the details, just blames dad for “breaking the family”. Won’t speak to him now, blocked him on everything, ignores all his messages. Says he never had a dad. It’s like he’s rewritten history.

He lived with mum until May but things had got really bad. She let him get away with everything – missed school constantly, weed from about 14, hanging out with older lads, no bedtime, no rules. She called it “keeping the peace”. He was her baby and she wouldn’t hear a bad word against him. He knew it too. The last couple years it turned properly toxic – swearing at her, smashing her phone, shouting in her face, threatening her, throwing stuff. She rang me in tears multiple times but still refused to involve social services. Said he wasn’t going into care and it was either me or dad. Dad’s in Germany and my brother won’t even speak his name, so that left me.

He said he didn’t want to live with her anymore. Said she was “too much”, called her pathetic, said he wasn’t her carer. She was scared of him by the end.

So he came to live with me, my partner, and our two boys – one’s 7, the other’s 14 months and has Down syndrome.

At first it seemed like a fresh start. He said he’d redo his GCSEs, go to college in Sept, started going to the gym with my partner, who was trying hard to be a stable influence. He was even getting on with the boys a bit. I thought we were turning a corner.

But then it unravelled fast. He’s back on the weed – every day – stinks of it, red eyes, out late. Vapes indoors even though I’ve told him not to. His room is disgusting – dirty clothes, dirty plates, bottles of piss under the bed. Won’t wash, won’t clean, won’t even open a window. Barely eats unless it’s sugar and junk.

He lies constantly. Even about pointless stuff. Steals – took my partner’s airpods, denied it even when they were sticking out his hoodie pocket. Refuses to follow any rules. Won’t contribute, won’t speak respectfully, just sits around sneering. Then if you call him out, you’re “bullying” him.

He gets angry out of nowhere, or just cold and weird. Can sit in silence for hours with a blank face, then suddenly explode over something tiny. He said something truly vile about my youngest the other week – “why bother with him, he’s never gonna be normal anyway” – and didn’t even flinch. Just said it and moved on. No apology. Like it was just a fact. I didn’t even know what to say.

He does things that make me wonder about ASD. I used to work in an SEN school as a TA so I’ve seen traits before. He stims – finger picks until he bleeds, rocks sometimes, gets really fixated on random things like certain foods, routines, very black-and-white thinking. Can’t cope if things don’t go exactly his way. He struggles socially too – either totally withdrawn or too intense. Doesn’t seem to get boundaries or tone.

I brought up the idea of maybe exploring if he might be autistic – gently, just as a possible support route – and he absolutely lost it. Said I was calling him a freak, smashed a glass, stormed out and didn’t come back for hours. Said I was just like everyone else, trying to label him. He won’t talk about it now.

So now we’re meant to be going to see our dad on Monday. He’s over from Germany and hasn’t seen us in years. I was looking forward to it – dad wants to meet the baby and see my eldest again. My partner can’t come cos of work so it’d just be me, both boys, and my brother. The journey’s brutal – train to London, Eurostar, then train the other side. About 9 hours door to door.

My brother was reluctant to agree to the trip from the start. Said he didn’t care, didn’t want to see dad, had nothing to say. So I mentioned maybe just me and the boys going instead and now he’s done a complete 180. Full blown meltdown. Shouting, storming around the house, saying I’m abandoning him, that I’m just like mum. Told me if I go without him “don’t bother coming back.”

I’m exhausted. I don’t feel safe travelling that far with him and two young kids and no partner there to help. But if I leave him here, I don’t know what he’ll do – he goes missing when he’s in these moods.

AIBU to cancel the whole thing? Or just go without him?

I agree this young person needs help but OP is not in a position to give that help and she has children who should be protected. He is not her responsibility.

EggnogNoggin · 20/07/2025 21:21

Mate, I know you came to this from a good place but having him move in was, and remains, a terrible idea. You were a stable but removed presence to an unsettled teen.

Now you're in a situation where him living woth you is actually bad for your own children. Moving him out is best for them bit underlines his victim mentality of being abandoned. So if you act in your children's best interests, you're now been manipulated into perpetrator role.

You need to extricate yourself. You're not his mum. You can still be a sibling though.

Unexpectedlysinglemum · 20/07/2025 21:37

Ps - the only teen I have known to wee in bottles like this had mosaic Down syndrome. As you mentioned your little one, it just got my wondering, if that's something that your brothers doctor could

It sounds to me like whilst he's been really rude about one of your children, he doesn't pose a risk of physical harm to them. If that's right, then children's services won't be rushing to offer him alternative accomodation. They will want to support him to stay with you.

I'd contact your local drugs and alcohol service - they should be able to help you and would help him if he's open to their help. Weed = increased risk of psychosis in young men.

The volatile moods could be drug induced or could be puberty hormones or something else. A GP could help and ought to be able to do so without labelling him in a way he doesn't want.

It's worth thinking through what's gone wrong for him - as a small child he was ok so understanding what's changed is important - could he have been exposed to dangerous people by your mum? How did she treat him when she was unwell herself? Worth contacting your local young carers service - I can't imagine he's the only teenager who is no longer a carer and has complicated feelings about it.

This is definitely a safeguarding risk to your younger children. Your brother has mental health issues and substance abuse issues. He needs help. Contact social services, they may be able to help. He needs to see a Dr and stop with the weed.

To the ones saying I need to contact social services – I know. I really do. I’ve known for a while this is way more than I can manage on my own. But I’m scared. If they put him in foster care I honestly think it could break him even more. He already feels unwanted, like nobody gives a toss about him – I think it would confirm everything he believes about himself. That he’s a problem to be moved around or shoved out of the way. I know that doesn’t mean I should sacrifice my kids’ safety and my own mental health, but it’s not that easy in practice. I can’t stop picturing him thinking I gave up on him.

Someone asked what his explanation was about the urine under the bed – at first he said it was my 7yo (??), which obviously it wasn’t. Then when I called that out, he laughed and said he just needs to pee a lot and couldn’t be arsed going to the toilet. I told him it was disgusting and unacceptable and he just shrugged and said “mum didn’t care, she just left me alone so what else was I meant to do?” No shame, just blank. That sums it up really.

To the people saying I should tell him to leave – I get it, I really do. But the reality is he’s got nowhere to go. He’s adamant he’s not going back to mum’s and I genuinely believe she wouldn’t have him anyway. She won’t say it outright but she’s scared of him now and I don’t blame her. He’s not got any friends he can stay with, no other family. It’d be me sending him out onto the street and I can’t do that. I just can’t.

For the ones saying cancel the trip and ask dad to come to me – I’m leaning more and more that way. I should’ve pushed back on that sooner. It’s been left to me (again) to make this mad 9-hour trip with two small kids and a brother I can’t even trust to behave for an hour, let alone a whole day of travel. I’ve messaged dad this morning and asked if he’d consider coming here instead, even just for a day or two.

I told my brother again last night that we might not be going to Germany and he went into a massive strop. Said I was “leaving him again” and that he’s bored, has no one to do anything with, and everyone’s always making decisions without him. But he didn’t want to go in the first place?? Said he’s not getting on a plane ever so flying’s not even an option. He’s just all over the place.

He doesn’t have a job – he did a bit of work experience with my partner when he first moved in and was actually doing OK, learning bits and sticking with it, but we couldn’t keep it going because there wasn’t really anything regular for him to do. Since then, nothing. I’ve suggested part-time stuff, even just something like McDonald’s to get him out and around people, and he turned his nose up. Said he’s not working in “some fast food dump”.

And as for speaking to someone – mentally or physically – I really don’t think he will. He’s totally closed off to that kind of thing. Thinks it’s all crap. I’ve tried. But he either shuts it down or kicks off.

Anyway, sorry this is another long one. Just wanted to check back in and say thank you. I’m still not sure what I’m going to do yet but reading your replies makes me feel less alone.

If he needs a wee a lot he could be on ketamine

What on earth makes you think that?

He sounds utterly volatile, unstable and downright weird. A drug addled, unpredictable bloke with anger issues, whose own mother is frightened of him. Like fuck would he be sleeping in the same house as my kids.

TwinklySquid · 21/07/2025 23:48

You worry about his feelings about feeling like a problem but at the end of the day: he is a problem. His behaviour is foul and you should not have been put in this situation.

You need outside help. Maybe it will give him a wake up call.

Weald56 · 22/07/2025 06:16

You may love your brother, or feel sorry for him, or believe looking after him is your responsibility… but unless you prioritise your own children this sounds like a tragedy waiting to happen. Whether it’s social services or the police you need to call someone and kick him out. Pronto.

Pessismistic · 22/07/2025 18:46

Omg op what a horrible situation to be in. It’s good you took him in but he is becoming a problem maybe it’s best if your dad came to you and talk to him he is his son after all he is his responsibility even if your brother disagrees or get dad to put everything in writing and you make him read it before dad goes back to Germany but how much more can you take? How does your partner feel about him being there and being such a slob. Your brother might be lashing out but it’s your house your rules and it’s a huge responsibility for you to have especially with your own dc.
