To ask: have you ever had someone just stop speaking to you for no reason?

Yes. Had lunch with a ‘friend’, sent a text to say it was good to catch up, didn’t have a reply, texted again to say I hoped things were OK, no reply again. Gave up. Three years ago. Absolutely no idea why.

Not a hugely close friend, but someone I knew when our children were little (decades ago). We used to see each other at toddler groups and similar and sometimes at each other's houses. We always got on well, I thought. When the eldest children started nursery school we stopped bumping into each other naturally. I rang up in the hope of arranging a time to meet. Left a message with her partner. She never rang back. Fair enough, I thought she might just have forgotten. I waited a few weeks and tried again. Same result. Took the hint. She's moved on, that's that. Wasn't particularly bothered.

Then months later out of the blue she rang up. Very friendly and chatty, how were we, this is how we are, etc etc. Asked if I'd heard about a proposed local event near in the local park which she thought would be very disruptive. I hadn't and was concerned. We discussed what we could do and my husband and I then produced some leaflets and distributed them locally, lobbied some councillors, event was re-located. Result!

A few months later I saw her in the local park and went over to say hello. She was with a friend and the chill coming off her would have flash frozen a bag of peas. She never contacted or spoke to me again. Absolute user. I have no idea what I did to offend her in the first place but it's very clear she only contacted me again because she knew I was (back then) somebody who she could rely on to swing into action. I'd been involved in various community groups as an organiser and committee member. Pah.

Yes - a girl at my school who was the kind of girl who everybody wanted to be friends with but at the same time everyone was scared of. She used to decide each week who would be ignored, ie: "Sent to Coventry" and you would arrive at school and discover it was you when nobody was talking to you. It was horrible.

Yes. Gave her a job at a company where I held a senior role, trained her, became friends. Company was taken over, I was made redundant, she wasn't. She stopped speaking to me as soon as I left. Never heard from her since (nearly 3 years) even though I've messaged a few times to see if she fancies a coffee or to ask how she is.

No idea why.

Good friends, chatted by Whatsapp a few times a week, met up for a drink a couple of times a month. Last time we spoke was nothing out of the ordinary. No arguments and nothing bad was said.

Next time I went to message them, they'd gone from Whatsapp and I noticed they'd blocked me on Facebook too.

Asked a mutual friend to find out what happened but the ex-friend refused to speak about it. Mutual friend then had an argument with them saying their behaviour was out of order, so that friendship broke down as well.

Still have no idea why I was cut off like that.

Yes school mum friend. Started not including me on days out etc then stopped speaking all together. She has since done it to other mutual friends so think it's her issue not mine

Yes aged 15. A friend completely cut me off. I am 55 and still wonder why. It was awful at the time.

Happened to me with a work colleague after I had been off work with sickness.
Made me quite sad at the time but now feel they can't have been my friend in the first place. Awkward at work though sometimes

Yes and it was directly after I had given her a lot of support through something. I asked her about it, she denied it but then continued to blank me. I then ignored her back. She started sending me sporadic texts but being icy to my face.
I then told her I was cutting her out completely as I was sick of wondering if she was talking to me or not, then she went round and told everyone she was so upset because I had suddenly cut her off for no reason ( basically what she'd done to me). I never found out why she'd cut me off but she's very tight with another friend and I think she felt she couldn't keep up two friendships. I still have to see her regularly but I ignore her. She runs and hides away from me when she sees me like it's a big deal but I'm not arsed, I'm done and I won't ever talk to her again.

Yes - my whole family ! Narcissistic mother made up a huge amount of really really unpleasant lies. They all believe her !

There will be a reason though, you just aren't aware of it.

I haven’t had it happen to me and I wouldn’t do this to someone else. I think it’s terrible behaviour.
