My son stopped talking to his sister after finding out she was dating his best friend, and I don’t know how to fix this

I never thought I would be in a situation where my own children would become strangers to each other.

For context, I'm 46 years old and I have three kids. My oldest son is 19, my daughter is 18, and my youngest son is 14.

My oldest son has had the same best friend since they were 8 years old he is same age as my son. That boy has been part of our family for so long that I never really saw him as just a friend he was almost like another son to me. He was always at our house for dinners, sleepovers, holidays, and everything in between. I watched him grow up.

My daughter also grew up with him. They were the same age, went to the same school, and were always close friends. They would play together when they were younger, and as they got older they would go hiking or spend time together, especially when my son wasn’t around. I always thought they had a good friendship and that both of them were good kids.

About two months ago, my daughter came to me and told me something I wasn’t expecting she and my son’s best friend were dating. They had already been together for two months, and she told me it wasn’t just a small crush. They were serious about each other.

She was nervous telling me. The first thing I asked was whether my son knew. She said no, but she wanted to tell him herself and asked me not to say anything. I felt uncomfortable keeping something from my son, but I also felt it was my daughter’s responsibility to have that conversation with him.

My daughter is a very thoughtful person. She is not someone who makes decisions without thinking about the consequences, so I trusted that she had taken this seriously.

A month ago, my son found out from some friends that his sister and his best friend were dating. What hurt him the most was not only the relationship itself, but that everyone seemed to know except him.

He asked my daughter why she didn’t tell him. She explained that she was scared he would react exactly the way he did. She wanted to wait until she knew the relationship was serious because she didn’t want him to think it was just a temporary teenage crush.

My son was furious. He told her that she shouldn’t date his best friend and that things between them would never be the same. He also confronted his best friend, who tried to explain that he genuinely cared about my daughter and wasn’t playing around.

I understand why my son feels betrayed. His best friend was like a brother to him, and now he feels like that friendship has changed. He has also felt responsible for protecting his sister since their father passed away five years ago.

But I also told him that while his sister should have told him sooner, she did not do something wrong by having feelings for someone she cares about.

I can see both sides. My son is hurt, and my daughter feels guilty. She has cried to me because she misses her brother and doesn’t want to lose him. But my son is still angry and has completely shut both of them out.

It has been a month, and my two older kids barely speak. They act like strangers in the same house. I don’t want this to permanently damage the relationship between my children.

Its also a lifeling friendship for the daughter? And could become a lifelong partnership. What on earth is this weird “bros before hos” day at mumsnet. Is the best friend never to have a serious relationship lest the DS in this story suffer another “loss.”

I'm sorry, have you read the umpteen replies demonising the son?
This is his best friend since childhood. What he is feeling, especially regarding being the last to find out, is totally normal.
It affects the dynamic of his relationship with his best friend. Or is it just the daughters feelings that matter?

Again, have you read the replies about a 19 year old who lost his father just like his sister did?

I will say it again, as I have said repeatedly since I joined Mumsnet. This site does not value friendship at all and you will never get a response supporting it above a romantic relationship.
Which is why the majority of posters have no issue demonising the son.

TourdeCrema · Yesterday 14:02

Its been a month and your son has had time to come to terms with the fact his best mate is dating his sister

they haven't done anything wrong by becoming a couple in a relationship and at the start of relationships many people keep it secret until they know themselves whether they are going to move forward

Your son now needs to look at how he is going to be mature about the situation, he is allowed to feel a bit awkward but he can't control other peoples feelings and emotion, which are perfectly natural

Your daughter and best friend haven't done anything wrong
your son has feelings about this relationship but to not work through them and adjust to the situation is wrong

RockinCara · Yesterday 14:04

If they’d have told him earlier it sounds like he still wouldn’t have been happy.

They both need to apologise for telling other people first, but stress that they only didn’t because they thought he would be upset and they were worried. They should both say they care very much for him and it won’t change anything if they are together or if they split up. And the best friend needs to make sure he does plenty of things with his friend as well as his sister.
You need to tell him you understand why he’s upset, but that he needs to settle down and accept it. Tell him he can’t control other people and it’s silky/sad to fall out with two people he loves because of this.
Hopefully it will then all calm down. Have they watched Friends? Reminds me of Monica, Ross and Chandler!

Again, she knew this was going to hurt him. That is the only reason she never told him. Or maybe, from his perspective, he feels like he was not that important to her or his best friend, because she told her whole friend group but not him.

Of course, it is her life, and she can decide whatever she wants. But now she also should not expect the same old treatment from him or expect him to behave like nothing has changed.

What I can see is that, at least to him, they were both very important people. She is his sister, and she started dating his “best friend.” Nobody calls someone their best friend without having a very close relationship. That is why he feels he should have been the first person to know.

Anyway, if that is the truth, then my son learned this the hard way and sooner than he expected. I’m only saying this based on the same logic you are using.

She didn’t tell him because she was scared of him. She clearly said she was scared of him getting hurt and that their relationship might be damaged, and unfortunately, that is exactly what happened.

No, he is not abusive, physically or emotionally. I know my son better than you do. Keep your assumptions about him for your own situation.

Friends will support their friends, and I don’t think their support makes my son a bad person.

It has been months since he stopped talking to them, and honestly, he is doing okay. It is my daughter who got hurt and is crying now, and as a mother, that breaks my heart.

Kindly, stonewalling is abuse. It is a form of coercive control. Please intervene before your son grows up into the kind of man who normalises it.

Your DD and the friend fucked up. They're 18, they're very likely to split. To keep it a secret has made it 100 times worse. And in the meantime ruined your DS' relationship with his best friend. I feel for your DS the most here. He's realized he doesn't have his best friend anymore at an age where friends really matter.

JulietteHasAGun · Yesterday 14:05

Your son obviously thinks his bf is a decent guy. So he should be happy his sister is dating a decent guy???

I disagree. Sometimes you're just upset with someone and don't want to talk to them. Why should you?

For months? Living in the same house?

Anyway, coercive control is written into UK law. You can look up the arguments for and against why.

I would be treating it as seriously as if my son were kicking over bins, or doing light kleptomania.

Maybe the best friend had the the best idea why NOT to tell someone who can keep up silent treatment for a month because ego

Imagine the hurt of not only being told by someone else that your best friend and sister are in a relationship, but of finding out that they were so indiscreet that the whole of your friendship group knew except you. Had DD told him herself - or even her and BF together - the chances are DS would have been more accepting of the relationship, and hurt at being blindsided by hearing it from someone else wouldn’t have been a factor. I think the hurt has been the main driver of his reaction and I think he’s entitled to time to himself to process and come to terms with it.

IkeaJesusChrist · Yesterday 14:08

I'd be telling DD and BF that they created this mess and they can deal with the consequences.

Out of all the people in the world they decided to start fucking each other, without caring that the brother would essentially be losing his best mate a few years after losing his father.

It doesn't make the son controlling or gay for being angry that he has been made a fool of and was the last person to find out, neither of them had even the decency to tell him, instead they told their entire friendship group and crept around him.

Platlete · Yesterday 14:10

OP do you see that your son’s response to this situation indicates that he could be a very difficult possibly abusive partner? His response to this direction is to be “furious”, highly dramatic and shut out his sister and best friend. I would be concerned about his character as he sounds quite unpleasant.

Bridesmaidorexfriend · Yesterday 14:13

Mumsnet never letting me down with unhinged responses…. Anyone who is vehemently calling out either your son or your daughter are ridiculous.

Neither your son or your daughter are being unreasonable. They both could have handled it better but they’re teenagers. Life will move on regardless of whether they’re together or split up. Yes your son is right, their relationship might never be the same again but that’s life. Your DD can date who she wants, but she knows that this impacts her brother, not saying that should have stopped her but she made that choice. Keeping it from him is probably just a stick he can beat her with because he was upset, he would have been upset regardless.

Let them all get on with it, I don’t doubt it will all settle down soon enough. Although I might tell my son that he’s cutting his nose off to spite his face. He’s losing those relationships that he’s so upset at the prospect of losing because of his sulk. He will feel better if he gets on board

ruolocretaw · Yesterday 14:14

Your son may be hurt that he was the last the find out, but he needs to be mature enough to understand why they were reluctant to tell him. His behaviour now has only made it look like they were correct to worry and be uncertain of how to broach the subject. What's done is done. He needs to understand that he wasn't kept in the dark out of spite, but rather out of fear that he'd be upset.

Your daughter has done nothing wrong in dating her brother's friend, and it's shameful that he's behaving as though his friend was somehow off limits. It's not at all rare for young women to date their brothers' friends (or for young men to date their sisters' friends). If it changes things between he and his friend, that's just how it is. Friendships started in childhood inevitably evolve, anyway, so if it hadn't been this, it would've been something else.

Why is he losing his mate? His mate is right there, he’s just refusing to talk to him.

Why are his feelings any more valid than anyone else in the situation?

It is not indiscreet to choose who you want to tell. It is exercising choice.

Sulking is not processing.

Punishing a sibling so her romance is all mixed up with tears and having to choose is twisted.

It sounds like the brother was going to be 'hurt' anyway. Why can he not learn to be happy for others and accept change?

He’s 19. He’s processing new and mature emotions. His sister and best friend shared the fact that they were in a relationship with the whole of their friendship group and neglected to tell him, so he was blindsided, hearing it from someone else. They’ve behaved very badly in allowing that to happen. He’s deeply hurt and he’s decided he doesn’t want to talk to either of them for the moment. I think they need to respect that. I think this is more about processing his feelings and deciding how to move forward than coercive control and OP lecturing him about his ‘abusive’ attitude isn’t exactly going to help the situation.

LBFseBrom · Yesterday 14:17

This will pass, honestly. If it lasts, your son will come to terms with it in time. A month is not very long.

I do get why son feels the dynamics of his relationships with friend and sister have changed dramatically but he'll get used to it. This is all part of growing up. He'll find someone himself sooner or later and will understand then.

harriethoyle · Yesterday 14:20

You need to stay out of it.

Your son feels like he's been made a fool of - and he has been, finding out from others. That was disrespectful of both sister and BF. I can understand why he feels an important safe space has been taken from him.

Your daughter should have been mature enough to raise it with him. If she had this might not have blowen up because he wouldn't have the perceived humiliation.

Don't meddle or get in the middle. They'll have to find their own balance.

We should not base whether we do the right thing on whether we think others will. The right thing is still right. That is how you have a strong and ethical centre. (I admit it took me a while to learn that, so I don't blame teens for being a bit crap...)

Exercising a choice to tell the rest of the friendship group and not him is fine (well it isn't imo but ok) but now the consequences are that he doesn't want to speak to them because he's angry.

Who says he sulking? Maybe he just doesn't want to talk to them yet and there have been times where I've not wanted to talk to my siblings and wouldn't have wanted to be forced to.

...silent treatment for months?
sister and best friend already walking on eggshells?
making their relationship all about him?
...
loss of father?

counselling or mentoring by someone independent is in order, not lecturing by OP.

19 is old enough to have been in the army for 3 years.

OP hasn’t indicated that DS is forcing either of them to ‘choose’. And of course it’s indiscreet if you tell your whole mutual friendship group about the relationship and deliberately leave one member of that group in the dark. In what world did either of them think he wouldn’t find out ?

I don’t think he’s punishing either of them. I think he’s been blindsided and he’s hurt that as the one closest to both of them he was the last to know, and from someone else. I think that hurt is what has been the main driver in his reaction. Why can he not be left alone to process that - he’s 19 and these are all likely to be new emotions way beyond the maturity of his years. He needs time to come to terms with it and move on before he can be happy for them.

I don’t think your daughter has done anything wrong. She knew he’d kick off and he proved her right.

I suppose one day they’ll break up and your son will decide if he can get over it or they’ll stay tougher and your son will decide whether he can get over it.

Neither the daughter nor the best friend were honest.

I'd say the son is right to feel aggrieved that he has been lied to by two people that should never have lied to him.

That's the betrayal.

If they'd told him up front and he was kicking off then I'd say he was in the wrong.

In this situation sister and best-friend need to grovel and it may still not be fixable.

There are echoes of finding out about an affair that everyone else.knew about - making you seem like a fool as well as betrayed.
