To end this friendship?

I’m being asked to support someone and I can’t. It’s a long one.

Basically, my friend was in a long-term relationship with my BIL (DH’s brother), they met through me. She has always known that he did not want any more children (he has 2 with his ex-wife). She has, until recently, been fine with it- at least publicly. Obviously, I cannot know if she has secretly harboured other wishes but she has never given this impression (and, in previous relationships says she did not want children, so I’m inclined to think this is a change of heart). According to BIL, he has always been 100% clear that he does not want any more children and has never suggested he might change his mind- until recently she has never suggested she was unhappy with this situation. However, recently she decided she does want children. BIL’s view remained unchanged.

A few months ago friend had an “oops” pregnancy- I believe she deliberately stopped contraception without saying so (I.e. planned a pregnancy) based on something she said to me and my other SIL- but she quickly backtracked when both of us were fairly horrified at the “sometimes you just have to make it happen, if you get what I mean” comment.

I would agree she has the right to stop contraception any time she likes, but she should be honest with her partner as it’s a mutual thing if no contraception is being used. Equally, I think both parties have to accept contraceptive failures do happen. But deliberately not using it without saying so is utterly wrong and a huge betrayal of trust, in my opinion.

BIL had a vasectomy very quickly (privately) after he found out his partner was pregnant- against her wishes- as he was adamant he does not want more children. I think he probably should have done it sooner, but equally don’t think it unreasonable that he trusted his partner to take the agreed contraceptive. He was accepting of a contraceptive failure, though he was honest about the fact that he was not keen to keep the baby. He was obviously prepared to shoulder his responsibility to the baby, despite his lack of enthusiasm. I think this is totally reasonable.

Sadly, friend had a miscarriage at 14 weeks. She was, and is, devastated by the miscarriage. I do feel for her- despite the circumstances- and I know BIL’s palpable relief at the outcome probably made it harder for her. But, equally, I think he is entitled to his own feelings and never pretended he was excited to be a father again. Obviously, I have never said that to her- that is just my thoughts.

Anyway, I’d said to DH about what she’s said and that I thought this was very off. DH also thought that what she said was suspicious. It seems other SIL also told her husband. After he thought about it for a short period, he spoke to his other brother- and both decided to speak to BIL. This was around the same time friend miscarried. He told DH he had some suspicions but given events had decided to give her the benefit of the doubt (especially as it cannot happen again).

Anyway, he was devastated to have his suspicions supported and that his partner would do this- he confronted her. According to him she initially denied it, but eventually said she had accidentally messed up her contraception but had just not said anything, so it wasn’t planned in advance (he doesn’t really believe this and thinks it was a very deliberate choice, probably been the case for some time). However, even if it was a one-off slip, she still chose not to say anything which might have meant BIL would have used a condom or abstained- she apparently admitted to him that she thought he would have done one of those things if he had known the reality of the situation. He has ended their relationship. As they aren’t married, she is going to be in a significantly worse financial situation as she has no claim on any assets or their home.

I am in an awkward situation- I do feel sorry for her as she is understandably struggling with the miscarriage, the end of her relationship but equally think she has behaved terribly towards her ex-partner, who is a member of my family. She’s furious with me/us, but equally wanting support and for me to “speak to” BIL to convince him to give her a second chance.

I genuinely can’t do the latter- I think it’s not only not my place, I believe he is right to end the relationship. I can’t apologise for the former, as I don’t think it was fair to ask me to keep this to myself. In short, I don’t really think I am the right person for her to lean on right now. I think our friendship is essentially over. I think it was over the minute she admitted what she had done- I feel that if she understood me, she should have known what I’d think about her actions, and how I’d feel about being asked to keep it to myself when it is a member of my family impacted. I genuinely do not know why she told us/suggested this if she did not want anyone else to know.

Her mother contacted me to say how much friend is struggling and how worried she is about her mental health, and also how disappointed she is that I haven’t been there more for her. The thing is, my friend just wants to rant about what a POS he is to have dumped her weeks after a miscarriage, making her leave their home etc. our friendship group is split- I’d say 3/4 agree what she did was utterly repugnant, and she put myself and other SIL in an awkward situation by telling us and expecting us to say nothing. The others feel that what she did “wasn’t ideal” but that she doesn’t deserve to lose her relationship, home etc over it and the miscarriage should have bought her some grace. This is going to cause problems in our group. I’m ok with this, although I am
sad as we’ve been friends for a long time, as others are entitled to their views.

I do feel sorry for her regarding the miscarriage, but I also think she is the author of her own misfortune and will have to live with the consequences of her actions. Her actions have absolutely rocked BIL too- he feels utterly betrayed, and is finding the violation of trust really hard to come to terms with. I just can’t pretend I’m ok with what has happened. AIBU?

Tbh even if you didn’t say anything, SIL might have and you’d look awful for not speaking up.
Your friend can’t blame either of you.

And morally you’re right.
It’s best to step out now.

and her relationship was better coming to an end anyway, she wants a different life to her BIL.

Blue18273 · 07/11/2026 22:04

It’s a mess, not saying in anyway what she has done in right but I would say your stepping into land that 100% isn’t your business, who knows what conversations they have had behind closed doors. It’s not for you to navigate how they go forward but it feels like you feel it’s for you “to decide” what continues and what stops.

Genevieva · 07/11/2026 22:06

Unless something was a state secret, I think most people would naturally tell their spouse. Sharing is a core component of marriage. It also sounds like it was a throw away comment, not a hushed secret. It was only looking back on it that made you reevaluate what she said.

Anyway, regardless of all that, you ivipusy can’t be her shoulder to cry on. You are too close to the ex. She needs a bit of distance. It’s a shame it’s blown up her entire frinsgip group, but perhaps one of the 25% is patient enough to listen to her until she grows tired and moves on.

I don’t think you’ve put a foot wrong OP. What she did was outrageous.

People saying you’re too involved, bullshit! It’s your family for gods sake!

And those saying he was irresponsible with contraception are frankly nuts. It was presumably agreed that they would use the pill as their form of contraception and she concealed “making a mistake” (don’t believe that for a second by the way). He did nothing wrong!

I agree with this.

By this logic every man would have to say to his partner "I don't trust you so I insist on using a condom".

What would that do to a relationship?

Jimmyjumpy · 07/11/2026 22:41

If she is your friend then you should continue being her friend but make clear a few ground rules about what you wont discuss.

acron · 07/11/2026 22:58

On the one hand, BIL was totally clear about not wanting more kids. And your friend tricked him by not using contraception correctly, very deliberately. This is very bad behaviour from her.

That said, she was obviously desperate to have a baby. It’s very easy for those of us who have got children with a partner who did want them, to judge a woman who gets into a situation where she desperately wants kids but is with a partner who doesn’t. It must have been driving her crazy.

And a 14 week miscarriage must be utterly devastating, regardless of the circumstances.

But it doesn’t seem like the best person to support her is you. It’s your dh’s brother, he’s done nothing wrong and he’s taken action to get someone who betrayed him out of his life.

Boreded · 07/11/2026 23:13

LemonPuppyPorkChop · 07/11/2026 18:06

Bluntly, it’s not the OP’s business. I don’t disagree that what the SIL did was ethically wrong, but her husband was also irresponsible about contraception in the circumstances. I’d have told her that what she did was appalling, that she should tell her husband the truth, and that I didn’t want to hear another word about it, or any potential fallout, and taken a step back, because I’d be questioning my own judgement about having this person as a friend.

The OP is dealing with this precise level of family/friendship mess because she didn’t take it up with her SIL at the time, and told her exactly how poor her behaviour was, but tattled to her DH behind her back.

The choice wasn’t between ‘pretending it was fine’ and betraying your friend’s confidence to your DH.

The fact that you can acknowledge that what she did was appalling, yet still find room to criticise her husband for being “irresponsible about contraception” when he believed they had an agreed method in place, is quite extraordinary.

He wasn’t irresponsible for trusting his wife. She deliberately exploited that trust, knowing full well that he would have made a different decision about having sex had he known the truth.

And describing the OP telling her own husband about the potential reproductive abuse of his brother as “tattling” is an astonishing trivialisation of what actually happened.

You’re entitled to believe that loyalty to a friend requires keeping her secrets, but confidentiality isn’t some absolute moral obligation, particularly when the secret concerns serious wrongdoing against another person.

The OP didn’t create this mess by telling her husband. Her friend created it by deceiving hers.
It’s genuinely remarkable how determined you seem to be to find fault with everyone except the person who actually committed the deception.

dermalermalurd · 07/11/2026 17:58

I cannot condone her behaviour, at all. But I am struggling to see your intervention as justified. I’d say butt out of other people’s relationships. It has all blown up way further than it needed to or would have done without your intervention.

Totally agree with these posts.

why on earth are you all so involved in another couple’s contraception issues? You’ve said you can’t get involved in helping your friend repair her relationships but you certainly could get involved when you all informed her husband of something she told you in confidence.

All sounds a bit too righteous.

Boreded · 07/11/2026 23:20

Overflowingbasket · 07/11/2026 18:13

I agree with this. Tbh none of you come out of this looking good.

My view, whatever the rights and wrongs of how she became pregnant - and men having sex with women do have to accept they might get pregnant - she is suffering terribly now. She is grieving a much wanted baby, the loss of her relationship and the loss of her home. As well as it, it looks like, some of her friendships. This is a hugely destructive and traumatic amount of loss for anyone to go through all at once and in one stroke. Her mother is right to be worried about her.

I certainly would not get involved in trying to recover her relationship, but I would absolutely be there for her as a friend.

“Whatever the rights and wrongs of how she became pregnant” is quite a remarkable way to gloss over deliberate reproductive coercion.

Yes, men having sex with women have to accept that pregnancy is a possibility. What they don’t have to accept is their partner deliberately lying about contraception because she knows they wouldn’t consent to sex under those circumstances.

If a man deliberately sabotaged contraception to get his partner pregnant against her wishes, would you be so quick to dismiss it as simply one of the risks women take when having sex?

And I’m struggling to understand exactly what the OP has done wrong here. She told her husband that his brother was being deceived. Apparently that’s enough for you to conclude that she doesn’t come out of this looking good.

It’s quite something to see more criticism directed at the person who exposed the deception than the person responsible for it.

If he didn't want a child he should have used condoms or had a vasectomy. He needs to take responsibility for that.

Im not saying she didn't do wrong but people do stupid things when emotions are involved and yes she'll have to live with those consequences but all friends turning their back on her is intentionally cruel. She hasn't deceived you, so why do you need to be so cruel?

Why on earth should he have used condoms or had a vasectomy when he was in a long-term relationship with someone who had assured him she was using contraception?

He’d made it perfectly clear that he didn’t want children. She knew that, which is precisely why she lied about using contraception. He’d have used condoms or refused sex if he’d known the truth. And your response is that he should have had a vasectomy? Would you tell a woman whose partner had deliberately sabotaged contraception that she should have got herself sterilised if she didn’t want children?

As for “people do stupid things when emotions are involved”, we’re talking about deliberate reproductive coercion, not a momentary lapse in judgement.

Her miscarriage is tragic, but it doesn’t excuse her actions, and it certainly doesn’t mean her partner is obliged to stay with someone who betrayed him.

And why should the OP be expected to remain friends with someone whose behaviour she finds morally reprehensible? You don’t have to be the direct victim of someone’s actions to decide you want nothing more to do with them.

JLou08 · 07/11/2026 18:26

I'd rather have your friend in my life than anyone else in this scenario. Yes, she messed up but for you and SIL to pass on that comment, which wasn't even an outright confession, was really, really shitty. Your husbands passing it on around the time of her miscarriage was shitty. Your BIL ending the relationship and making her leave her home just after a miscarriage was unbelievably heartless. You to not want to support your 'friend' through this is also heartless. I'm going to guess you and SIL weren't that keen on her being a part of the family before this happened.

I think that’s rather unfair on everyone involved, particularly the BIL.

He’d made it clear that he didn’t want children, and his partner deliberately concealed the fact that she wasn’t using their agreed contraception because she knew he would have made a different decision had he known.

That’s a very serious betrayal of trust, not simply someone making a mistake. I don’t think it’s reasonable to expect him to remain in a relationship after discovering something like that, regardless of how unfortunate the timing was. Of course her miscarriage is terribly sad, and I have every sympathy for what she’s going through. But that doesn’t mean the BIL’s feelings or his right to end the relationship should be disregarded.

And I don’t think it’s fair to criticise the OP for reconsidering a friendship after discovering someone has behaved in a way that goes so fundamentally against her own values. You can feel compassion for someone without wanting to remain friends with them.

There’s a difference between seeing things in black and white and recognising that some behaviours are simply unacceptable.

You can acknowledge that she’s suffering, have sympathy for her circumstances and still recognise that what she did to her partner was appalling.

I’m perfectly capable of seeing the nuances here. I’m just not prepared to use them to excuse reproductive coercion.

Which part of what I’ve actually said do you disagree with?

Livelovebehappy · 07/11/2026 23:30

I think far too many people seem to be invested in this. I mean, saying lots of friends and family have opinions on this and have been discussing it, is a lot. She hasn’t behaved great here, but a lot of people seem to have lot of input and a lot to say.

VoltaireMittyDream · 07/11/2026 23:32

Surely the friendship is over anyway?

I think conceiving by deception is awful, and I also think your family sound like a bunch of shit-stirrers and busybodies.

My comprehension is perfectly fine, thank you. Perhaps you could try addressing what I’ve actually said rather than resorting to insults.

I haven’t suggested you think her behaviour was acceptable. I’ve questioned why you described the OP telling her husband as an “outrageous betrayal of confidence”, blamed her for the resulting mess and even criticised the BIL for being irresponsible about contraception.

You’ve now gone from calling the disclosure outrageous to saying the OP’s reasons were understandable. That’s quite a change in tone.
And what exactly was the OP supposed to do if her friend refused to confess? Keep quiet indefinitely while her husband’s brother remained unaware of the deception?

You seem far more interested in the OP’s motives for telling the truth than in the fact that someone was deliberately deceived in the first place.

You can acknowledge that the friend’s behaviour was appalling all you like, but it doesn’t explain why you’re so determined to find fault with the people who exposed it.

Perhaps instead of questioning my comprehension, you could answer the questions I’ve actually asked.

I haven’t insulted you, merely questioned your reading comprehension. I was responding to what the OP disclosed in response to my questions in subsequent posts. She admits her telling her husband was in part motivated by pure self-interest, because she thought it was going to come out and that he would blame her for having known and not told him. She was covering her own ass.

And yes, I think that changes my response to her decision, if she didn’t interfere voluntarily in this mess — if she felt forced to tell because she thought it would have dire consequences for her own marriage when it became known that she’d known.

I’m still interested in when exactly her DH told his brother, whether it was before or after the miscarriage.

Oh, questioning someone’s reading comprehension isn’t intended as an insult? How very convenient.

So now you’re saying that the OP telling her husband was understandable because she was concerned about the consequences for her own marriage. I’m glad we’ve established that, although I’m not sure why her motives make any difference to whether telling him was the right thing to do.
She could have been motivated entirely by self-interest and it still wouldn’t make the disclosure wrong.

And you still haven’t explained why the BIL was irresponsible for trusting his partner about contraception, or what the OP should have done if her friend refused to confess.

You seem determined to dissect everyone’s motives and behaviour except those of the person who deliberately deceived her partner.

As for whether the disclosure happened before or after the miscarriage, why would that change whether the BIL deserved to know the truth?

ThatLemonBee · 07/11/2026 23:57

Your friend has just lost a baby on her second trimester. Having had a miscarriage before I would say her MH trumps anything right now and if you can’t see that then you were never truly her friend . Bol being upset aside ( and I can completely see why by he did what he did) . She is still in need of true friends . If you cannot be one just leave her be but you have never been a friend in the full sense of the world

Savvysix1984 · 08/11/2026 00:05

Nobody looks good in this scenario.

your friend should not have intentionally tried to get pregnant knowing her partner didn’t want a baby. Thats morally wrong on so many levels.

her partner should’ve taken proactive steps to prevent pregnancy independently of her- condoms or vacesctomy and not relied on her.

you should’ve kept her confidence and said nothing as it was none of your business. She was suffering a miscarriage.

right now I’d do nothing as you’ve already done enough. Let the dust settle for now.

AIBU?

I think the whole situation is very sad all round. I suspect this woman didnt think through how bad her actions actually were. But I also think the brother in law didnt really love her. I think someone who really loves another person would sit down with them and discuss why it was such a foolish and disrespectful and selfish thing to do. And then see if that other person could truly take on board the terrible mistake they had made.
