To be annoyed about DP saying my brother has ruined our holiday?

I'm currently away in Spain with DP, DD4, DS1 and my brother (22), I'm quite close to my brother and he comes over often when we're at home.

In the past he has struggled mentally, he's also T1 diabetic and while as a teen he ate alot of sugary things and didn't do his insulin and as a result he was very unwell. He's also got a habit of drinking too much which he can't do and he was once left by his ‘ friends’ when he had q hypo so I do worry about him lot, even though it's well managed he can make silly decisions especially when struggling.

Our mum mentioned to me before we left that he had been acting off again but he was saying he was “fine”, I hadn't noticed anything but I obviously kept it in mind.

We got here Saturday and it was already off to a bad start due to our flight being delayed, yesterday was good until last night when brother disappeared without saying where he was going. It turns out he was in a bar drinking on his own.

Long story short, he had a hypo and was argumentative when I was trying to help him, DP had our children with him and I was with my brother, he was eventually fine but I stayed with him in his room to keep an eye on him. He's spent the day in his room sleeping off his hangover

Dp wasn't pleased about me staying in his hotel room as the baby kept waking and he said “so much for a relaxing holidays” (as if we could get one with kids anyway) and was annoyed that he hasn't joined us so far after we paid for the holiday and has said it's like having another kid but instead we have a manchild acting like a moody teenager so tonight we've argued because he's annoyed that I'm obviously worried about my brother
he's now stormed out too after saying he's ruined the holiday

AIBU here or is he?

Even after the event he's hiding out instead of coming out and apologising to his sister and BIL though... and she's making excuses for him. He's not a bloody child. He did something wrong (he knows the health consequences) and isn't owning it.

Maybe if he got up, apologised, promised not to drink again and tried to get on with the holiday instead of wallowing and causing arguments between the people who.paid for his holiday then people would have more sympathy.

I agree he definitely could have handled it better.

I've caught up on OPs replies and it sounds like her brother manages stuff fine most of the time.

It does seem to me that her DH isn't helping much and part of his annoyance is he was left to respond to his own child in the night instead of OP doing it and has now started sulking and given her the silent treatment when there's plenty of holiday left to get things back on track. His behaviour isn't great either and Op is stuck.in the middle trying to do her best.

Of course going out drinking alone isn't a good move. Yes he SHOULD behave responsibly to keep his levels in check. We both agree on those points but for whatever reason and we don't know the full picture, her brother isnt doing those things and this is where he's at. He needs understanding, support and hopefully he'll get on track. Tough love is hard to deliver when the consequences may actually be dying in his sleep.

And what will happen if the sister isn't there?

I very much understand the complexities. Babying this adult like the op’s there there approach would never ever fly in any of the T1 cases in my family.

Well its lucky no one in your family needed a different approach.

I know alot of families living with T1. Some have had no issues what so ever so far. Its takes work but they do all the right things and get on with stuff no problem. There are others that for various reasons they struggle more or they have more than one diagnosis that layers the complexities. The people that have repeated hospital admissions are the ones that were left to get on with it when they were diagnosed or when they were struggling.

My own experience is in the middle. My child has had it since she was a toddler. On the whole she manages it amazingly well. She does loads of sports, travels with friends etc but due to other stuff going on in her life she has occasional blips and yes I am there to help support her when that happens. I don't enable her, she knows the health consequences, its her body, its her life but sometimes people need some extra support and understanding. It's not even about T1 really.

OPs brother has ruined the holiday according to her DH but there's a bigger picture here and I applaud OP for being there for her brother.

loislovesstewie · 03/06/2026 06:36

I do have understanding of T1. My adult DS has had it for 25 years, since the age of 11. I'm still saying that the OP is being unreasonable. Yes it's sad, yes it's difficult, yes it can cause depression. But at the end of the day, anyone with T1 has to take control and do what is best for them in terms of the condition. I understand that sometimes despite doing all the right things, hypos happen. For that matter hypers can happen too. But going out alone drinking to excess isn't a good move. It could result in death as most people passing by will see a drunk young man, not a drunk person having a hypo. It's his responsibility, ultimately, to behave responsibly, even if that means he can't do some things.

YABU @Lisatron. You are enabling your DB to continue his irresponsible behaviour. I am not a bit surprised your DP is annoyed .

temperedolive · 03/06/2026 07:59

He did ruin it.

I'm diabetic too, and I get it. It's not fun to have to be vigilant all the time, deny myself things others can have, etc. But like all health matters, even if it's not my fault it IS my responsibility. If I go into DKA on a holiday, then what?

To be fair OP you've asked for opinions on a site where most won't understand the complexities of a young adult living with a chronic illness like Type 1 diabetes.
You sound like a fantastic sister trying to help your brother out and you are doing the right thing being there for him and definitely staying with him when he had drank too much. Type 1 is relentless- 24/7 and it sounds like your brother is burnt out and is making poor decisions. Its well known how much the condition can impact mental heath because of how relentless it can be. Never an off button day or night.
Its a shame its affected your holiday but I have empathy for you and your brother because I have a similar issue in my family so I do have personal experience. I would say the opinions of people that have no understanding of this condition are irrelevant.
I hope your DH comes round as its support and understanding you need aswell. What's your brother diabetes team like - do they offer support and would he accept it?

My son was diagnosed Type 1 aged 25. Fortunately he took the medical advice to heart and I’m so proud of him. Hypers and hypos are dangerous as you are aware and so should your brother be. He must take control of his own life and not depend on others to bail him out if he acts irresponsibly. I understand your concern for your brother but your main concerns are your children and husband. I’m afraid you’re being unreasonable in this instance.

Your son was a fully grown adult at 25 when he was diagnosed. Most people with T1 are children and teenagers - it makes a huge difference. Everyone is different aswell including insulin resistance and management of the condition. Its great your son is managing but its not the same story for everyone so all people with the condition shouldn't be lumped in the same boat.

I don't see the holiday as ruined, tomorrow is only our 3rd full day but dp going off and sulking is ruining the holiday

I’d imagine he sees it as ruined because the first couple of days have revolved entirely around your brother rather than your DP and children and your DP was under the impression that your brother would babysit so you two could have some time together. And now he doesn’t trust him not to drink alcohol. I wouldn’t want to leave my children with him either. He’s probably sick to the back teeth of you and your DM running around looking after him when he knows he shouldn’t be drinking.

And; tomorrow is only their third full day. If brother being a twat hasn’t ruined it then dh sulking hasn’t either. Stop with the double standards op where your brother can do no wrong but your dh is ruining your holiday.

Brother isn't an alcoholic. He very rarely drinks but sometimes he does want to when out with friends, I have no idea why he drank on his own yesterday.

Your DP would not be off in a sulk if it wasn't for your brother's behaviour and subsequently your own behaviour.
Big enough to go out drinking, he's big enough to manage his hangover by himself. You could have popped in and out over the day, you didn't need to stay with him, he's not a small child.

You are putting him in front of your children and husband.

You obviously don't like what's been written here but you really should reflect on how you behave.

Laurmolonlabe · 02/06/2026 23:19

I'm afraid I'm with your DH on this one , you shouldn't be leaving your 3 children to look after an adult brother who really should know better. You can't stop your brother making bad decisions- he is an adult, you really shouldn't have taken him on holiday.
Picking up the pieces is not your job and you really don't have the option of putting yourself in that role when you have 3 children under 5- that is more than enough responsibility for anyone- you are endangering your relationship and your children , by attempting to parent an adult who doesn't want to change.

Skates · 02/06/2026 21:04

So let me get this right. You paid for your brother to go on holiday knowing and after your mum warned you he’s drinking and not looking after himself. Then you spend the first night on holiday looking after your dick brother who’s gone and got drunk leaving your husband to look after the kids all night. Seriously. Your brother is a selfish twat and you’re stupid for enabling him to act like this with no consequences. Next time leave your brother at home and have a holiday with your family. Your husband has every right to be thoroughly pissed off with you

Inviting a 22 year old male relative with responsibility issues on holiday to babysit for him.

Clearly the brother wasn't babysitting and that's not what the DPs problem was. It was that the holiday was ruined because the petulant OP and Brother needed to leave the family for drink issues.

mamaE123456 · 02/06/2026 20:47

Why on earth did you bring your brother on holiday with you? And pay for him to come? If he was going to help you have a nice holiday, fair enough, but it sounds far from this!

WhereTheWeatherSuitsMyClothes · 02/06/2026 20:20

BudgetBuster · 02/06/2026 17:37

Having said that, both the men in OP's life need to grow up a bit, take more responsibility for their actions and situations they put themselves in!

What situation did OPs husband put himself in exactly? He was the one on on holidays minding their shared children while OP had to mind her stupid little drunk brother

AluckyEllie · 02/06/2026 20:18

Imagine your DP bought along his sister. She went out, got pissed and your DP vanished to look after her all day leaving you with both kids on the second day of your holiday. Which is meant to be family time- but you prioritised your manchild brother over your partner and kids.

He’s been a diabetic for years, he knows how to manage it. Apologise to your husband and get on with your holiday.

I don't think your partner is being reasonable. I think he's adding to the problem rather than contributing to moving forward and being a bit dramatic about one night.

It's not unreasonable for your brother to go to a bar by himself and not unreasonable for him to want time away from the rest of you.

There is some harm reduction advice for diabetics who choose to drink alcohol - it's worth finding it. Different alcohols have differing levels of carbohydrates. There's a huge lack of understanding about the impact of diabetes on 'normal' rites of passage - somebody of 22 should be able to get drunk on holiday with the most likely consequence being a hangover.

If your brother can't manage his own hypos he's at risk of not being allowed to drive for a while. It's worth thinking about where he is - able to manage but it's easier if you're around or unable to manage without someone else's help.

What you can do: really clear communication about which activities you're doing together / who is responsible for which children and when/ what alone time everybody gets. It's obvious from that that you can't be drunk in charge of children. Remember it's everybody's holiday. Unless you agreed in advance with your brother he was on call for childcare all the time, it's not fair to expect him to remain sober the whole time.

You might be able to model safer alcohol consumption for your brother by having wine with meals / spirits as a nightcap if you also drink alcohol.

His diabetes nurse / one of the diabetes charities may be able to help with adjusting insulin if it's getting hard for him to work out the adjustments needed for the time change / different temperatures / less familiar foods if he's trying to count the carbohydrates. His reaction to alcohol at the bar may be exaggerated because of the other stuff meaning it might be less bad later in the week once he's acclimatised. I bet the diabetes nurses have 'cheat sheets' for less intense concentration on diabetes management at times when that's too hard. 'diabetes distress' is worth looking up.

It's not unreasonable for your brother to go to a bar by himself and not unreasonable for him to want time away from the rest of you.

Of course it's not unreasonable for the brother to want some time away. But it is completely and utterly unreasonable for him to get so drunk when he knowingly has a medical condition and ends up with his sister opting to spend time away from her young family to babysit him. That's completely unacceptable.

Your brother has behaved like a dick. He’s young and he will learn. I don’t blame your DP for being annoyed tho, he’s spot on in what he’s said. He shouldn’t have to worry about your brother. Terrible idea to bring him on holiday and it isn’t fair on your husband or your kids. YABVU and owe your husband an apology.

This - your DH has every right to be annoyed, your DB has got a free holiday to help with babysitting instead you are babysitting him !

Hangingcrystal · 02/06/2026 18:52

I have a son of 22 and I think your brothers behaviour is selfish, juvenile and annoying.
It's a free family holiday and he is causing drama.
I think your partner should have realised that this was a possibility.
I wouldn't dream of giving him responsibility of my children.
I wouldn't be bringing him on holidays again either.
Your brother needs to be told cop himself on.
He sounds extremely self absorbed.
This is a family holiday and your children should have your attention, not your childish brother.

I certainly wouldn't be happy in your partners shoes.
He wouldn't be joining me on holiday again.
Have a bit of understanding for your partner or you could be storing up relationship trouble.
Your brother isn't your responsibility.

I had a brother like yours and he ruined a couple of years in my 20's with his bullshit and drama.
He dumped on me rather than our parents.
Age 30 I was done and told him I was finished being his free therapist.
It was a huge relief.
He was fine.
I wish I had told him early to cop on and grow up.

Beware of infantilising him.
