fake confession...... am at a lost how to advice dd

Try what? If you mean the sarcastic riposte, do not encourage her to do this. It could, and would backfire spectacularly and she would end up in a worse position and looking very silly. They certainly wouldn't be impressed by her cool. It might have worked in a film but, you know, that was a film.

Lose what?

People who treat her badly?

Please just tell your DD to stay away ftom them. Block them. Don't engage. They aren't worth s moment of her time.

It's famous for Millennials! Not kids nowadays.

No! She is not a keeper. She lied to your daughter.

Yes they are bullies! What are you talking about? You don't want her to lose what she has with the girl? Well she already has! The girl is a massive dickhead and a bully. Try to encourage her to find some easy going friends and that being with the popular kids isn't worth it.

It’s a quote from the movie and anyone questioning could be told as such. It’s a very, very famous movie that people quote all over the internet to this day. In the movie it’s revealed that the very popular girl used to be friends with a more unpopular girl but pushed her away under the guise of “I think she is a lesbian/I think she has a crush on me.” She tries to shame the unpopular girl for this. The unpopular girl reacts in this funny/sarcastic way to mock the popular girl and everyone loves her for being bold. She isn’t a lesbian but she doesn’t care who thinks she is.

It’s widely believed the popular girl may have been the one questioning sexuality and this is why she made a show and pointed fingers and ridicule at the other girl. Perhaps this is true also for your DD’s “friend”

It’s you again - the poster who is a teen or pretending to be a teen posting from an adults perspective. Don’t you get a bit bored of doing this?

The best thing she can do is ignore them, it doesn't sound like she will have the confidence to pull off a sarcastic comment like this.

You need to start teaching your daughter that there are people in life who are good for you, treat you well and are well intended but there are also the opposite.

You need her to realise she has a value and if people doesn't make her happy, treat her well and respect her, then she's better off without them

It won't be the last unpleasant incident in her life but she needs to have the self confidence and self esteem to deal with these things. If she feels good about herself, she will become more resilient and won't get bother by this sort of nonsense.

Look, these girls are not friends.

Dd should be discouraged from thinking that they are, and not encouraged to hang out with them. The girl who does seem a friend may well be nice, but she is clearly not strong enough to make the other girls stop, and is weak enough to stay with them rather than dump them for their shitty behaviour to be a proper friend to your dd.

help your dd to find other friends, even outside school, rather than be the butt of their jokes.

I think you should encourage your DD to pick up her hobbies or start a new hobby so she’s busy and doesn’t dwell on what has happened. None of these girls were good friends and they might have been using your DD for sport. It’s tricky to tell.

also you need to get you and your dd some extra support to deal with the ASD. Are there some local groups you could go to? Look it up online.

I'm truly sorry for your daughter, OP, but it does sound as if both you and your daughter are quite naive. If they were using her for entertainment, i.e. laughing at her not with her, then none of them are nice, including the "friend". I had a very similar situation at the same age but 50 odd years ago. I was part of the It crowd, until suddenly I wasn't . It's a horrible feeling, not knowing how long people have been being nasty about you behind your back. But I mustered my dignity, walked past them into school and to my amazement, found there were other people who wanted to be my friend and who I had much, much more in common with. Believe me, I wasn't a confident or tough shelled girl, but I did it and my last 2 years at school were my happiest.

I mean that you could have put in your OP that your DD (and now I see yourself) are neurodiverse.

Your daughter needs support from trusted adults (e.g you) to navigate confusing social situations.

I get that you don't want to believe that the girl is complicit in the bullying of your DD because that will be hard for your DD to take, but that is the reality.

You can't shield her from this. You shouldn't want to shield her because in ignoring the signs of abuse you set her up to be taken advantage of and abused in the future.

What you can do is teach her resilience. Yes it hurts when people are shit but we are ok, we bounce back, it feels awful but we recover and heal.

OK, so she would need another person to help her out with this and who she feels she can trust. I am sorry you have been given a hard time here OP. You being ND (possibly) explains alot. People can interpret your absence of dealing with this as they would have as you being lazy/neglectful while you in reality have problems navigating relationships yourself.
Is there anyone in your family who can help out with this? Does your daughter see a counsellor who she can talk to? This must be very stressful for you OP, I'm sorry. Some of the smartest People I know are ND but they are very clueless socially and really need help to separete the "good and the bad eggs".💗

Just tell your DD to stay away from all of them. It’s quite possible that the first girl was genuinely nice and did like your DD, but the group as a whole are bullies and this one girl isn’t going to pick your daughter over the group.

Support as in a sounding board to help her read people's intentions. She obviously talks to you so I would take it you could help her navigate relationships. That being said, are you ASD as well because you sound pretty unaware of group dynamics and the risks of being bullied?

I really don't understand why you are still struggling to see what's going on.

No, "the girl" isn't a keeper. No, you should not be encouraging this friendship. No, friendship groups don't talk about dating their besties. No, friends don't use others for entertainment.

They know your DD is vulnerable and are bullying her. Your job as a parent of a vulnerable teenager is to stop your DD from being a victim and get her away from these girls. None of them are her genuine friends.
