Sorry if this is a long one. Me and my brother have a history of me feeling very upset, hurt & belittled. I can't comment on how he feels, but I am guessing that it involves anger & re sentment at loss of control.
The synopsis isn't word for word, but it is not enhanced. We have had plans for weeks to go and see my brother and his family. Very much looking forward to it and I have lots of things planned, plus birthday presents and little gifts to bring. The dates needed to be changed (at their request) so I had to cancel plans at home and reorganise things with my ex.
One was a class. My lovely SIL messaged me to say her child was going to the same class on the morning we arrived, so I thought great I will book my kid on too. She gave me the details of the place, I said I was booking it, then said I was waiting for the woman to get back to me, then all booked on. Several messages over several hours. This got a thumbs up. I then got a message from my brother saying I had bulldozed my way into a private arrangement, my SIL had arranged to meet friends there and I had missed the social cues (he hadn't read the message exchange in our group WA at this stage). I exclaimed why hadn't she told me any of this, it was a niche situation that I couldn't of envisaged I would try and cancel, but had already paid. I was upset by his wording, but let's draw a line under it as I was hurt and I didn't want to upset SIL. I was told to 'wind my neck in' I had been challenging & argumentative and not to come at the weekend as he didn't want to argue during his only time off. Who would be arguing? Just sleep on it and get over it! I did the whole are you serious, my little one would be devastated, we had plans with my sister as well and I had organised all these things. I got a 'refer to earlier messages' and a 'yeah I can't be bothered'.
I am thinking that he new how upset all the kids would be and doesn't give a flying I can't be around someone who cares so little about my child.
We have managed to salvage some of the weekend and I am still meeting with my SIL & Sister, but I am still upset and feeling quite anxious today. I have a history of really bad depression and anxiety. My brother did have the option to still come, but changed his mind at the last minute. I was willing to play nice & hope that it made essential family gatherings easier in the future. Stupidly I had even dreamt of an apology.
In hindsight and looking to the future, this relationship has often left me hurt and shaken. He appears to love control, feels superior and will just switch on me. I have told him that there this is it for us now and blocked him on everything as I just can't discuss it any further (probably childish, but it will only get worse). Previously we had gone for long periods of no contact and only really had a relationship again since he procreated.
So should I just stay far removed and try an keep a relationship with my SIL and their kids, which is what I want. Or is there another option?

(This has formatted a little strangely. I hope it is ok to read).

Why do you want a relationship with any of them? Your sil caused all this by complaining to your brother about the plans you’d made with her approval?!!! I
wouldn’t trust her to not actually be raking the situation!

Because if I don't see her, I will never see my nieces again and we do actually get on.

I agree with trying to keep a relationship with your SIL and nieces. Though may not be easy without your brother and you being in contact.

I thought the same!

@Namesuggestion101 your brother was repeating your SIL!

He’s still a massive arse though, but so is she I’m afraid.

Not enough for her to want you to spend time with her friends!

PicknStick · 24/05/2026 21:37

@Namesuggestion101 how does your brother treat your sister?

InterIgnis · 24/05/2026 22:15

Hmmm. I’d be inclined to think that your SIL didn’t want you to also sign up, but like a not insignificant number of mumsnetters who struggle with telling people ‘no’, went along with it to you but then complained to your brother, someone who doesn’t struggle with telling people ‘no’. At all.

I do think you should probably take the hint when it comes to your SIL, just from the thumbs up emoji tbh. It doesn’t exactly give the impression that she was overjoyed at you signing up.

Your brother wasn’t particularly delicate in how he approached the issue, and your SIL could definitely work on being assertive, but I also think it would have been better to let her be the one to invite you if she wanted you to join her,
rather than just invite yourself along. It doesn’t seem like you have the type of relationship where this would be a non issue.

Nogimachi · 24/05/2026 23:07

It sounds as if you and your brother have a communication problem. Either that or he is unstable.

It may be worth trying to unpick your communication issues - but he does sound pretty horrible if he is using language like “wind your neck in” after you’ve explained there was a misunderstanding.
Your SIL is at fault for giving you the details of where she was going!

nomas · 24/05/2026 23:17

It’s hard to see the context without the messages, but did you ask SIL if your child or did you just say you’re booking it? You should have asked first

Regardless, your SIL should have said she already has plans to attend with friends.

Your brother sounds unpleasant. If you’re doing all the running around after him and SIL, it might be time to take a step back and consider what you’re getting out of these relationships.

Namesuggestion101 · 25/05/2026 04:36

Just to clarify she gave me details of how to book. I thought she mentioned it because I had to cancel my daughters class to go and see them. Yes that part was a miscommunication, but she had hours to explain. Minutes after I paid and told her I had done so, I get a message from my brother. He hadn't bothered to read the messages in the group chat before starting with the insults, then he tried to put all the blame on me. He cancelled without giving a f* even after I explained this would really hurt my daughter. I can't be around someone who care so little for her.

It must be possible to have a relationship with just your SIL unless she is a pushover and unable to be honest and thinks the way your brother does. It’s hard to know, but in any case he sounds dreadful and YANBU to have nothing more to do with him.

Thank you. I did manage to see her with the girls this weekend, she gave me a big hug and we had a nice time. I just know he hasn't shown her our messages and will have told her what puts him in a good light. He cancelled without talking to her about it.

In the end, through my tears, I told him he is not a nice person & seems to take pleasure in hurting people. This is the me being unreasonable part. He has done some lovely things for me in the past & vice versa, but I think I need to look at the bigger picture. My mum & sister seem to be quite support of me this time.

I don't understand why your not mad at your sil. You don't need to officially go nc and make a big statement just naturally cut your time with both of them.

SalmonOnFinnCrisp · 25/05/2026 06:02

Honestly I'd give the pair of them a wider berth.
Drop the rope completely with him and I'd only meet sil.and her kids on neutral terms and would not be going out of my way or bending over to accommodate.

Eg. Sil id message directly.and say "hey in June we are going on a day out to X (somewhere equidistant or just convenient for you). If you are free so you want to join?"

Or "hi sil hope all is well. Lmk if you want to catch up in summer - happy tonhost a play date/bbq for the cousins. We are free x or y dates. If you have lots planned no sweat"

Stop fighting for a relationship a d putting so much effort in. Let sil make the effort/ do some legwork

Canoodler · 25/05/2026 06:06

Your brother sounds like a horrible bully who gets a dopamine hit from making you feel bad. If that went on through your childhood he could well be the main cause of your depression and anxiety. My advice: cut or reduce contact and completely disconnect from him emotionally. Shut him out of your heart and just avoid him like you would a dangerous dog.
And have therapy to talk it through because you are worth it.

Thank you, there are many reasons for my D&A, but I think you are right, this has been going on since childhood and he does get a hit from it, all part of feeling he had the upper hand. Tha k you for your kind words.

You are so right. I think I need to take a step back and let her initiate any meet ups for a while, or even if she bothers. I think we will only be doing things with other family for a long time, and only if he is not there. I am still anxious and upset, but I can also feel the beginnings of relief edging in. Hopefully in the end this is for the best and it will be emotionally freeing.

Good luck. I avoid all contact with my older brother for similar reasons. Wish I had done it years earlier.

DeepRubySwan · 25/05/2026 06:47

Yeah just keep seeing your SIL and nieces. Your brother is an arse and she may need your support in the future.

I hadn't thought of that, but you are right. She is strong willed, but they argue a lot and I wouldn't be surprised if one day he just walks!

Sounds like my brother actually and all I can think of is he never liked anyone playing with his toys as a kid so doesnt like people being friendly with his wife. I booked a lovely thing for me and his then fiance and invited her sister and mother along for her 40th. It was not on a work day, would not have affected him at all and he roared and screamed I was being manipulative etc. Same person said absolutely horrendous things to me when I booked my mothers (agreed with my sister) trip to another country to see her. Again didnt concern him but he likes to project all his vitriol towards me for some reason. He was in an accident years ago and it was me he didnt talk to for over a year which is bizarre.

Your brother seems to just like to bully you for whatever reason, maybe jealousy, insecurity on his part, whatever it is but I would walk away now or at least put firmer boundaries in place. I have no contact with my brother now and even when I feel I miss him I remind myself he doesnt even acknowledge my teenaged son out of his spite towards me. Not a call, not a text at xmas/birthdays. He will end up alone because he will end up projecting his bitterness to his wife and I will totally back her up if he does even though I havent had contact with her in a few years either. Nasty spiteful men will never change. You do not deserve to get roared and abused by anyone op least of all a sibling.

Crikey'yes they do sound a like. I think a lot of it is habits from childhood. Thinking he is Billy big balls, and trying to assert himself. Classic little man syndrome. I just need to come to terms with my decision now. Thank you x

@Namesuggestion101 my brother is also a short man so yes, little man syndrome. Now we have narcissistic mother so she was always dripping poison in one of our ears about the other but he chose to be like her I guess. Shes also a very vindictive person. Sorry to hear you are going through this it is very hard.
