Was this really a friendship dealbreaker?

Another friendship thread, I'm afraid, but I think both people involved could use some perspective please!

First time posting and trying not to be outing, but potentially throwing a match on a car crash here!

Best friends for over 30 years. Extremely close, despite not living near one another. Basically family at this point.

They share a special interest and go to see live events together whenever practical. Friend A is diagnosed neurodivergent, Friend B suspects they are, so it very much is a special interest for them both, which is relevant. For the purposes of this, let's say motorsport.

They tried to arrange dates for some upcoming races together, which was a logistical nightmare given their different family commitments, but they had several provisional dates in mind ahead of tickets going on sale.

Friend A mentioned they also intended to try to get tickets to one additional race to attend separately with their teenage son, as this is something Friend A had wanted to do for a long time.

To be clear, this wasn't proposed as instead of attending races with Friend B. Friend A was considering going with their son on a date that Friend B could not attend, due to prior commitments.

Friend A still wanted to go to several races with Friend B, as normal.

Friend B said that they would consider Friend A attending a race without them a friendship dealbreaker and told Friend A not to book tickets to go with their son.

Friend A said that they valued the friendship enormously, but also felt they should be able to experience a race with their son.

No more was said about it and the friends continued to plan their trips together.

When tickets went on sale, they successfully booked tickets to a couple of races on dates that were mutually convenient.

Each friend had booked and paid for one of the races they planned to attend together and were excited to go.

Afterwards, Friend A managed to get tickets for the additional race with their son and, wanting to be honest with Friend B, told them.

Friend B was extremely upset and told Friend A that they hated them. Friend A apologised for Friend B being hurt, but would not apologise for wanting to have this experience with their son.

Friend B effectively ended the friendship on the spot and there has been no contact since. This was months ago.

To avoid dripfeeding, historically the friends have always exclusively gone to these events together, with the exception of when Friend B's father has joined them several times (he is in a wheelchair now and unfortunately unable to go anymore).

Both friends have teenagers who have expressed an interest in going over the years. Friend A has made attempts in the past to include them, but Friend B has always maintained that they prefer that the races remain something the two friends do exclusively together.

So now both of the friends own a set of tickets to upcoming races that they had intended to see together and a 30 year friendship seems to have ended quite abruptly!

Who, if anyone, is being unreasonable here?

Was Friend B right to be upset with Friend A for crossing a line, as the races were their thing?

Or was Friend A right to want to share a special interest with their son, whilst continuing the friendship tradition?

And given that Friend B had explicitly said beforehand that this would be a friendship dealbreaker, was Friend A unreasonable to go ahead anyway?

Does either friend owe the other an apology in order to save a 30 year friendship, or should both accept that there is no coming back from this?

Hopefully that all made sense!

For voting purposes:

YANBU = Agree with Friend A (you should be able to see a race with your son separately)

YABU = Agree with Friend B (the races were special to the friendship and you have effectively chosen your son over me)

I meant to vote YANBU.

Friend B is an idiot. Now you can take your son to the races that B doesn't attend.

ThatGladTiger · 08/09/2026 20:55

Friend B is being ridiculous.

I get it’s a thing you did together and maybe if friend A invited friend C it would be seen a different way. But wanting to experience something with your son is absolutely OK.

I would let this friendship go sadly! You can’t reason with people like this so I wouldn’t bother trying. What will happen with the events you’ve booked together? Are they seated next to each other or general entry?

Catza · 08/09/2026 20:55

If I it happened the way you said it happened, then friend B is insane and should be told that they do not have the right to control or monopilise a relationship in this manner. Not sure why ND diagnosis is relevant.

Credittocress · 08/09/2026 20:56

Whichever one A or B wrote that is the unreasonable one. Have a headache trying to keep up.

Really not that complicated

DahliaDelights · 08/09/2026 20:59

WTAF?

Nobody is gatekeeper of an activity i enjoy, not a chance in hell I would accept Friend saying I was forbidden from attending the event with my son WHEN THEY WERE UNABLE TO ATTEND. Thats absolutely batshit crazy.

Dozer · 08/09/2026 20:59

Friend B is U.

If friend B has chosen to exclude their family and other friends from the activity, that’s their choice. Wanting to impose that approach on friend A and to be friend A’s sole companion when doing the activity is U.

Greengage1983 · 08/09/2026 21:03

Friend B is being WILDLY unreasonable. You can’t control what your friends do for fun with their own kids, wtaf?!

nomas · 08/09/2026 21:05

YANBU, you were right to tell B the truth. A fun activity with your son shouldn’t be a secret you keep from a friend. You would always have been conscious of your words, worried she would somehow find out.

She maybe has some childhood issues with not being prioritised and tried to make that your problem. Stuff that. Sounds like you are well rid.

Justbrieme · 08/09/2026 21:06

Friend B may have ended the relationship but their behaviour is why relationships typically end.

ChessieFL · 08/09/2026 21:07

Friend B is being very unreasonable.

Changingplace · 08/09/2026 21:07

Friend B is nuts and ridiculous, you can’t gatekeep an activity like that, very odd behaviour.

Hellodarknessmyoldpal · 08/09/2026 21:09

Friend B is unreasonable. Assuming you’re friend A?

Endoadnowarrior · 08/09/2026 21:10

Friend B is being unreasonable
They couldn't go to the event that A is going to with their son anyway!!
And friend B used to occasionally take their dad - Double standards!
I could understand friend B being slightly miffed if Friend A had bought tickets for her son for the SAME event they were going to together as that would likely change the dynamic.
But going independently, nah, friend B has no right to demand this.

Pinkissmart · 08/09/2026 21:14

Was it an all weekend event where the son attending would massively change the dynamic?

Grasping at straws here

Ooodelally · 08/09/2026 21:19

friend B is a knob.
why have you wasted 30 years being friends with such a total penis?

Barney16 · 08/09/2026 21:20

Friend B is quite odd tbh. Completely unreasonable.

Dollymylove · 08/09/2026 21:24

Friend B is a CF.
Get rid

pizzaHeart · 08/09/2026 21:28

Friend B is very unreasonable. I think they are ND that why they demonstrated such a rigid approach.
Ime they won’t change their mind so friend A should plan visits to the races without them.

nowimabeliever · 08/09/2026 21:31

Friend B is crazy and should seek help.

But it is way too long and the letters pointless

BibbityBoppityTwo · 08/09/2026 21:37

Completely childish of friend B. Telling someone anything other that a serious betrayal or instance of disrespect will be a “friendship deal breaker” is something I’d maybe expect to see in my 13-year-old’s friendship group, not from grown adults.

The trip with the son is a third, totally different trip. Just for A and Son.

Booked on a day that B couldn’t have attended anyway.

The other two trips are for A and B only, Son is NOT going to those ones and never was.

you struggled to keep up with that? It was well written and extremely clear.
