Ds overstepped by showing his brother how to shave

YellowstonePilot · 02/03/2026 19:07

I have 2 boys 20 and 12 (13 next month), DP isn't eldest bio dad but he's been in his life since age 3 and he doesn't see his bio dad as he was abusive. He calls DP dad and when he turned 18 he changed his last name to DP’s. He always wanted dp to adopt him but unfortunately he couldn't die to his dad being on the BC and having PR. That was the only problem, I know DP happily would've and he doesn't treat the boys any differently

He takes eldest to watch football with him (youngest doesn't care for football) and he was really supportive when DS was struggling mentally as a teen and those years were HARD. They do clash as they're both as stubborn as each other and refuse to back down/admit they're wrong something that does bother me and I generally leave them to it as I know what they both are like. Eldest has ADHD and autism (diagnosed) and I heavily suspect DP is autistic (as does MIL)

He doesn't feel he needs a diagnosis as it wouldn't change anything. All fine but they are very similar as I said

My eldest didn't shave until he was 15, he started puberty quite late and DP showed him (and spent about a year doing it for him), my youngest however has a deeper voice, is already quite tall and had a noticeable moustache

I was in hospital from the 20th of Feb until yesterday so I reckon DP was just stressed but I can't get over how he spoke to my eldest. My youngest was the one who phoned the ambulance for me and last week he hit someone at school so he's also having a tough time (he never has hit anyone or even misbehaved at school in the past).

I'm resting at home now, my eldest home and youngest wasnt at school. They usually
hang out together in one of their rooms and at their ages I didn't need to go and check on them. This afternoon at some point youngest asked eldest about shaving i don't think he directly asked him to show him but eldest needed a shave so showed him. Personally I have no problem with it and I don't think he needed anyone’s permission except youngest of course as it's his face

dp got home and went mad at eldest and accused him of over stepping, he had a huge rant at him and accused him of making ds hit that child last week as he always told him to hit people when he was being mad fun of (youngest always said no) and said if he loses his place at his grammar school its on him (I doubt he will as while it's a very prestigious private grammar school, ds got in on a bursery and this is the only time he's misbehaved)

Eldest is also gay and a few years ago he thought he was bi and youngest started saying he was bi too (he was about 9), we left him to it as he could be but also he could've wanted to be like his brother. Until tonight when DP brought that up saying how he was too young to be saying that and how he's too young to shave and he needs to be allowed to be a kid

He was quite harsh and news going on about it now. AIBU or is he right in that eldest did over step?

It seems like your DP has been storing up a lot of angst with your eldest son. I'd be quite concerned that he's paying lip service to being his father figure.

INeedAnotherName · 02/03/2026 19:54

You have a DP problem and it's a very big one. Big enough to implode the whole family for good.

I know you are seriously unwell OP but DP being this way can't have come out of the blue, this has been brewing over several years.

EmbroideredGardener · 02/03/2026 19:56

Your eldest ds sounds like an amazing big brother

Yoosee · 02/03/2026 19:59

Your partner is an arsehole and has just pissed all over what sounds like a lovey moment between brothers. Be very careful that your relationship with DS1 doesn’t end up damaged through your partner’s actions.

Owly11 · 02/03/2026 20:02

There's a lot of detail in your post and I am not sure why. Genuine question- what relevance does all that detail have to your question?

Sensiblesal · 02/03/2026 20:02

Its absolutely lovely that despite the age gap they have a great relationship & the youngest felt comfortable asking the eldest.

DP being a little unreasonable but can see from his side he probably thinks its a right of passage for dad to show the sons how to shave

Bringyourfoldingchair · 02/03/2026 20:06

I feel really sorry for your eldest. Please don’t let your H treat him that way.

Because it's all relevant to my OP. Otherwise i’d be accused to drip feeding and many posts asking if he's eldests dad.

You're kidding yourself that DP treats them the same. He isn't DS1s father and you've been very naive to let yourself think he can act as if he is. Ds1 showing ds2 how to shave is a lovely and normal big brother thing. If you and DP had a DS3 I can guarantee that DP would have no issue with DS2 teaching DS3 to shave.

DP doesn't like DS. He is going to always put ds2 first. I think you need to have a very honest conversation with DP. You're stuck between a rock and a hard place and I'm really sorry. Hopefully you can have a good conversation with DP to try and find a way forward.

How is it relevant to whether he should have shown his brother how to shave?!

GertrudePerkinsPaperyThing · 02/03/2026 20:16

Oh my god how awful of your DH. My heart goes out to your poor DS1 in such a horrible and excluding living situation.

Oldandcobwebby · 02/03/2026 20:17

I'm a bloke and a dad. Your DP is so far out of order, he's on another planet. I feel so sorry for your poor boys.

Come on, you know full well people would have asked whether there was anything else etc and she would have been accused of drip feeding

YellowstonePilot · 02/03/2026 20:27

He isn't normally like this as I said they are close, he’s raised DS since he was 18 when we got together, I did introduce them quite soon which isn't advised I know but luckily it worked out and they are close so this has come out of nowhere. Yes they clash because they are similar but it has come out of nowhere

He was there for DS through everything to do with his MH and those years were so hard and just everything in general, his family have accepted him as their grandchild (which I see from a lot of MN posts that this doesn't happen often)

He's just adamant DS is too young even tho he did have facial hair,apparently he was 14 when he started shaving and it likely was his own older brother that taught him as he didn't see his dad very often and he and his brother are close in age (just a year apart) but he coincidentally can't remember

Absolutely bonkers response from your DP. Very normal for brothers to share this sort of thing. And he is very much able to show him again and give him tips. Fine if he is feeling overly upset or emotional about it. But to lash out and bring up your DS sexuality is pretty low. What a way to make him feel outside of the family.

hopefully he apologises when he takes a moment to think straight

QuayshhLawrain · 02/03/2026 20:31

YANBU. It sounds like your DH is just a bit put out as maybe he thinks he should have been the one to show DS2 how to shave. Nonetheless, he's totally overreacted here.

On your DS2 hitting another child at school; I wouldn't be surprised if this was a reaction to you being hospitalised @YellowstonePilot. 6 years ago I was very unwell, collapsed at home (which the DC unfortunately witnessed), ambulance called, 3 weeks in ITU. My incredibly well behaved DD2, who was 11 at the time, had some very out of character behaviours for a while afterwards, which counselling was able to unravel and explain as a reaction to feeling so out of control in relation to her Mum's health.

Your DH is particularly unkind to be causing so much drama when you've just been discharged, I hope you feel much better very soon.

katepilar · 02/03/2026 20:36

By the sound of it its a big thing for your husband. He should have sorted it when its so important for him. He is very unreasonable to have a go at your eldest. Its natural inmy eyes that the boy asked his older brother.

Send DH to therapy if he cant handle it himself.

sundaysurfing · 02/03/2026 20:36

In no way at all, did oldest over step - that’s his brother!!!!!

EvangelicalAboutButteredToast · 02/03/2026 20:36

Your DP is damaging the brothers relationship so I think he is being a dick. I would talk to DP and ask what the hell is going on with him and to explain himself. I’d then apologise to the two boys and explain DP was struggling with his son growing up.

SereneOtter · 02/03/2026 20:37

DP sounds like a nutter tbh.

80sbabyxx · 02/03/2026 20:40

When I was12 my big sister plucked my eyebrows- she was 19 she did them far too thin and I had lovely brows. Mum was mad at how she plucked them not that she plucked them iyswim because we are sisters we silly things like that...this was two brothers bonding your DP is a twat and doesn't look at your eldest as 'his own' knob

Translatethedog · 02/03/2026 20:44

Your Dh is jealous.

I agree with this.
When you say DP and DS1 clash because they are both stubborn and alike, I genuinely wonder if DP clashes with anyone else or just DS1? The examples you have given of DP sound like he is taking any excuse to have a go at DS1.

HaileyBailey · 02/03/2026 21:35

Your poor son. Your “D”P sounds awful.

GreenCaterpillarOnALeaf · 02/03/2026 21:41

Your DP is being a dick, and he needs to say sorry but from the sounds of it this is a one off. He seems to have been a good dad to your eldest, and he obviously cares about him deeply. You are all under a lot of stress at the moment and tensions are high. Your DP needs to say sorry to your older son - that’s not negotiable.

As for your other DS hitting someone, I know no mumsnet user has ever hit anyone and would never dream of doing so, but teenagers (especially stressed ones) often lash out. Given the context, I don’t think he will get in too much trouble at school - play the sick mum card if needs be. Bollock him a little bit, and bollock his older brother for giving him stupid advice and then leave it at tha.
