Patience going with immature friend

Spaghettihoops2026 · 06/01/2026 10:37

I have a group of about 5 friends who have all been friends for 20 years plus.

One of them has always been immature but over the past year it has for some reason really started to grate on me. We all turned 40 this year. The more the group grows up and moves to new stages of life the worse this one friend gets, but this week they did something that disgusted me so much I no longer know if I want to continue the friendship.

Examples of behaviour, but this behaviour is constant:

. We have a group chat for general catch up/ meet up arrangements/ kids birthday reminders etc. They text all day on chat then gets annoyed when people don't respond because we are at work.
. Whenever a serious conversation is being had ie: another friend was having some cells removed after a smear test and this friend in between our conversation with the others was saying things like 'ewwww you have to let someone up your vagina'
. Whenever anyone reaches a landmark- buying a house/ having a kid/ getting a promotion they change the subject back to themselves and start saying we are all conformists.
. I said the other day I was going to the garden centre and they started just repeatedly sending pictures of OAPs to my phone.
. Another one of our group befriended a single mum from school and bought her out for dinner and when she got home text my friend a genuinely lovely message saying how amazing it is we have a friend with learning difficulties, it gives her hope for her daughter. The immature friend has no learning difficulties.
. Had a tantrum two of the girls in the group went for drinks together and didn't invite the rest of us.
. I just took my youngest daughter to college open day and said friend spent the entirety of it texting me saying she needed urgent help until I left the room to call her and she went JOKING and hung up.

Typing this out it sounds insane, but it has unfortunately been normalised over 20 plus years, until now.

They live at home still, have a job which they keep being offered promotions in but won't take.

Half of the people that meet this person find them endearing in an entertaining way as it's like having a bouncy toddler around, the other half ask how we are friends.

This week she had a tantrum at a family members funeral because she wanted to cut a cake early, resulting in her mum crying.

I guess I'm looking for permission to end the friendship without sounding like a jumped up cow but I have had enough. I want to live my adult life with my adult friends.

Thank you. My husband keeps saying it's me growing up myself with no time to tolerate is as well, he hates her. She will ring up and say to me OH I JUST SAW YOUR BOYFRIEND FROM HIGH SCHOOL or things like that. I have been with my husband since 18 with three kids. If she requests me to come out and do something that I really don't want to do (i.e: go to a wine bar at 10pm because I am 40 with three kids and a full time career) she puts on a whiny voice and starts asking if he's controlling me. It really is tedious.

All your updates make me think that your friend is a twin of my ex friend!!! You need to step back and cut contact. If you can't do that, then reduce contact and just grey rock her from now on. I cannot tell you the relief I got from cutting my now ex friend out of my life.

Glowingup · 06/01/2026 14:09

Okay well stop being friends with her then 🤷‍♀️ It doesn’t sound like a good friendship really.

I still stand by my belief that she has undiagnosed issues. The tantrum at the funeral over food timings is especially telling. I suspect that for whatever reason, her behaviour isn’t motivated by ill-will but it sounds like you’ve reached your tolerance limit so I would distance myself if you don’t want to deal with it anymore.

This has happened. We have suggested everything. She sulks for two weeks, comes back and apologises then 3 weeks later its something else.

Urgh, she sounds awful, young given her enough chances. I'd block her and leave the group chat. Explain to the others you need to step back for your mental health.

Yes that does come across very strongly in your posts. So why are you still friends with this woman then?

As I said, it's been 20 plus years and it's only just for some reason dawning on me that it will never change. I have put many, many years into her asking for help and me giving it- as have the rest of the friend group but there is nothing reciprocated other than stupid comments. So I have held onto it in the hope that she would grow up, but hasn't and now its directly impacting my actual day to day I will be fading out the friendship.

I think it's considerably odder how many Mners have longterm friends they dislike intensely. If you're all around 40 and have been friends for at least 20 years, you've been friends since your late teens or so -- none of her behaviour would have been normal then either. Why on earth describe her as a friend, keep seeing her regularly, and enabling this behaviour?

As some one who has just shrugged off a similarly draining friendship. It’s exactly the same as an abusive relationship, they rarely start how they end up. In my case it was time and noticing how much my ‘friend’ enjoyed it when I was struggling and would disappear when my life was going well or shit on the good things.

disturbia · 06/01/2026 14:03

Your friend needs to grow up that is a horrible thing to say to a woman after an internal. Maybe call her out everytime she behaves like this and stop inviting her to things. You deserve more adult friends

I think so now, I have been SO lenient. A mutual friend recently got pregnant and the immature woman replied saying when did we all turn into conformist robots. I said does it not occur to you that people just want children? It's just all so weird and I have three hormonal teenagers and I have no time for it 🙃

I would just make a separate whatsapp group and not invite her to it. Let the other one die. Doesn’t like any of you like her. She won’t change op especially if shes in her 40s and behaving like this.

I do get a sense that you think you’re a lot better than her and you keep mentioning how much more mature and responsible you are so I’m really unsure why you keep being friends with her. Just cut her off if you don’t want to continue.

We all speak and have spoken to her. She has all the support. I am giving up on that view with her which I previously had as she kind of uses anything you say to help as an attack however you say it and then won't speak to anyone. We have tried kind, blunt etc- but when she feels aggrieved she will very much tell it how she sees it. I can't explain it properly but its all very entitled and manipulative if that makes sense rather than someone being sad and lonely.

In which case it really sounds like you have done all you can. Not all friendships are forever, we all grow up and change and it really sounds like you have outgrown this friendship. Someone else suggested starting a new WA group- this is a good suggestion. When she inevitably finds out and is upset, time for some brutal honesty.

Spaghettihoops2026 · 06/01/2026 13:57

grinchmcgrinchface · 06/01/2026 13:54

I think I would just block her this point. Maybe she’s mentally unstable rather than autistic?

i appreciate all the people who say they are autistic and dontyt behave that way, but it really is a spectrum. could be audhd, some of the traits can be found in people with adhd too and I am one of them.

maybe have a serious conversation with her. come at it with empathy and concern and not accusatory, im not saying you were accusatory but a lot of ND people are very sensitive to criticism. just an idea before you end a long standing friendship.

Purplecatshopaholic · 06/01/2026 13:57

Blimey, I would have faded this friendship out long ago, I just would have no patience for all her nonsense.

… how sure are you that she doesn’t have learning difficulties? Because it sounds like she does.

I completely agree with this.
Sounds like it’s just gone undiagnosed.
No one without difficulties surely would be doing some of the things you’ve mentioned?!
I feel sorry for her; it sounds like she’s got some unaddressed need. People who parent children with SEN often develop a radar, so I’m not surprised the new friends clocked her.

It's quite depressing how many people are saying she sounds autistic. Really? Autism isn't exactly the same for everyone. I'm autistic and don't behave like that. We're individuals with our own personality

Op, your friend sounds annoying and immature. Cut her off

I've known autistic people like her (ex school friend who I recently stopped being friends with in our mid-30s for similar reasons to the OP). It's like they struggle with social cues and what is appropriate and can come across as extremely immature. It becomes more obvious as people get older yet they seem to be stuck in their immature teenage years.

I know autistic people can be wildly different in terms of behaviour but just because you're autistic and are not like that doesn't mean that this person could also not be autistic.

Of course she could have something else going on entirely but I would bet money she is not neurotypical.

TheGrimSqueakersFlea · 06/01/2026 13:50

Glowingup · 06/01/2026 13:44

You personally might not behave like this but a lot of her behaviours are ones that are associated with autism like repetitive behaviour, being rigid about wants and expectations, inability to read social cues, struggles at work and struggles with relationships.

No. This is just people on mumsnet tying themselves in knots to diagnose people. Some people are just immature and annoying. People on mumsnet are very quick to blame bad behaviour on autism

GreyBeeplus3 · 06/01/2026 13:47

True knobby behaviour right there

Everytime- then comes back with an apology that still somehow blames us for the behaviour.

ThatCyanCat · 06/01/2026 13:49

I know you say she hasn't got any learning difficulties but it really does sound as if she has something non-standard going on, although I wouldn't like to guess what. This isn't just immaturity, it's really not normal.

That said, you aren't the doctor, and it would really have to be something very very debilitating for me to want to move on after she made such light of someone needing further checks after a smear test, or pretending something awful had happened on the phone as a stupid practical joke. Ruining a funeral is up there too. I don't think I could cope with this level of total shithousery.

This is my mother OP, many similarities. I tolerated her ‘quirky’ behaviour for years as calling her inappropriate comments out only caused arguments. She is never wrong, everyone is jealous of her blah blah. Always needing to be centre of attention- it is indeed exhausting especially when she would mock me for being sensible or ‘boring’. I sympathise with you. For posters mentioning ND, autism etc maybe she is BUT we cannot keep labelling poor behaviour blithely. There are many ND and autistic people who are perfectly pleasant.

This creeps in on the Elderly Parents board. Obnoxiously stubborn elderly people where it is suggested that they might have dementia. In reality if they have always been obnoxious and stubborn it is simply amplified in old age. Again, there are people with dementia diagnosis who are perfectly lovely.

I would add that you are probably also heading to the phase of life where you cannot tolerate BS behaviours.

Thank you. My husband keeps saying it's me growing up myself with no time to tolerate is as well, he hates her.

As many have said she sounds annoying as hell, but she also sounds deeply unhappy. Those who set out to upset others- and her behaviour is hurtful as well as annoying are generally hurting themselves. It sounds like she's probably not very happy with her own life. I find the best response to someone who makes a rude comment is 'are you okay' as it shows compassion but also demonstrates that the behaviour indicates that they are not okay. Perhaps she just really needs someone to talk to.

We all speak and have spoken to her. She has all the support. I am giving up on that view with her which I previously had as she kind of uses anything you say to help as an attack however you say it and then won't speak to anyone.
