‘AITA for telling my younger sister she needs to be less needy and c**ngy?’

This older sister shared her sibling struggle on Reddit, detailing her sister’s clinginess and the fallout of their confrontation. Here’s her original post, unpacking the emotional rift.

I (22f) have a sister (18f). We have a tricky relationship. I adored her when she was born and we were close until she got older and clingier. She always wanted to be with me and would beg our parents to make me take her places. They didn't ever force me though and it helped me a lot.

But she would always be so insistent even though she had friends of her own to hang out with, she would have times where she didn't want them and she only wanted me and would not like when I had other plans. Once I moved out I tried to forced the distance a bit more, hoping it would help.

I was tired of her wanting me to take her shopping, drive her places, pick up her friends and bring them all somewhere as well as her wanting so much of my time. We started having more contact again last year and I tried to be a little more firm with boundaries and stuff but yeah, she was inviting herself to my house or asking if she could stay for a weekend or a week or two.

She wanted to spend her 18th birthday at my house. I was going to stay with my boyfriend that week and she told me to take her with me. I said no and it became a problem. She wanted me to 'make it up to her' by letting her move in and so I decided we needed to have a talk.

I told her I love her but she needs to be less needy and c**ngy with me, that it's not healthy to expect me to drop everything for her, or to take her everywhere with me, and she needs to value the other relationships or they will fail.

It upset her which I did kind of expect but then she got mad and she told me I should just say I don't love her if that's how I feel. My parents aren't mad but they think I handled things poorly.. AITA?

Siblings shape each other, but excessive dependence can strain bonds. The older sister’s frustration with her younger sister’s clinginess—demanding constant time, visits, and inclusion—reflects a need for independence after years of pressure. Her direct call to be less “needy and clingy” aimed to set boundaries but wounded her sister, who felt unloved. The parents’ critique of her delivery highlights a missed chance for softer communication, though her intent was valid.

This mirrors challenges in sibling dynamics with imbalanced attachment. A 2023 study in Journal of Family Psychology found that younger siblings’ over-reliance on older ones can hinder both parties’ autonomy, especially when boundaries aren’t modeled early. The younger sister’s behavior suggests possible insecurity or unmet needs, as Reddit speculated.

Family therapist Dr. John Townsend says, “Boundaries with siblings require clarity and kindness; bluntness can clarify but also cut”. His insight supports the sister’s right to space but suggests a calmer tone might have softened the blow. The parents’ failure to address the clinginess earlier may have fueled the dynamic.

The older sister could rebuild by affirming love while reinforcing limits, perhaps suggesting therapy for her sister’s dependency. The younger sister needs to nurture other relationships.

Here’s what Redditors had to say:

Reddit dove into this sisterly showdown with takes as bold as a locked door. Here’s a roundup of their thoughts, sprinkled with humor—because even family feuds need a chuckle.

[Reddit User] − NTA. Boundaries are important, I would say that the conversation was worded poorly on your part but its also understandable given the circumstances. Even my wife and I need alone time from each other.

Its not normal or healthy to spend every waking second in someones company. I'm almost curious if there was some kind of trauma or event that occurred that is making her seek out your company exclusively and in such high quantities.

LadyMilenium − Honesty NTA your sister need start to respect boundaries maybe she need time to think for a while sorry My English is not the best.

Tessa_Kamoda − NTA.. My parents aren't mad but they think I handled things poorly. And how the heck should you have handled it better? Sis doesn't understand / respect your boundaries, thinks she is entitled to you, your time, to everything that involves a piece of you. What is this called, co-dependency? at least strange behavior.

Why didn't your parents teach her that you are not at her back and call, that you are not her personal maid, that you are your own person with your own wants and needs? Where were they to not notice this behavior, to not nip it in the bud? She always wanted to be with me and would beg our parents to make me take her places. They didn't ever force me though and it helped me a lot.

How nice of them. They didn't force you to make her every wish come true but did they teach her not to be this b\*ttpain, to let you be, to accept a simple 'no'? spoil the child (extra cookie) or spoil the child ('rotten apple' / nuttso nobody wants anything to do with). In the future just tell her 'no' and don't jade (justify, argue, defend, explain).

Let her crash against the wall of reality, hopefully she will learn that people have boundaries, that it doesn't matter what she wants, that she has to respect a 'no', that the world doesn't revolve around her. Why? worst case, she sets her eyes on a significant other and behaves with designated so like she does with you. Designated so would press charges due to harrassment and a restraining order, that's why.

ohreally86 − NTA and I don't think you handled the situation badly. She wants to move in with you because you said no to something and you owe her? What in the hell?

ChqiTea − I am a female with a younger sister who is very similar to what you’re saying. I can tell our personalities are different, because I can confidently tell my sister she’s f**king annoying. But some advice I would give to you is to blatantly say no. Say no and NEVER change your mind.

If she convinces you to say yes, she’ll do it again and again and eventually she will understand that you’re super lenient with her and the power will shift. I get being polite, but you’re being too polite. Devil on my shoulder: tell her to f**k off and anytime she shows up slam the door in her face and call the cops.

[Reddit User] − NTA, you’re doing the best you can without trying to hurt her. But you do need your freedom so you can be your own separate person apart from your sister.

TigerDude33 − I told her... she needs to be less needy and c**ngy with me, that it's not healthy to expect me to drop everything for her, or to take her everywhere with me, and she needs to value the other relationships or they will fail.

This wasn't necessary. You're trying to justify your decisions about distance to her. You don't have to. 'No' is a complete sentence. You get to decide how to spend your time. It's what grown-ups do. 'Letting her move in' is a wildly inappropriate response to not taking her with you to stay with your boyfriend. An appropriate response might be 'let's grab a bite and eat in the park.'. NTA.

USAF_Retired2017 − NTA. Your life is your life and it doesn’t need to revolve around your sister. She seems WAY too c**ngy and I think you handled it nicely. She will be fine. She needs to live her own life and get over herself. Sisters can be close, but it doesn’t need to be suffocatingly so.

CinnamonPumpkin13 − She wanted you to bring her on a sexy fun week with your bf? Do your parents have her in therapy? If not, they really should look into finding a psychologist for her. Nta.

mowiiness − Info: Did you yell at her or talk calmly?

These Reddit quips are firm, but do they hold the key? Was the sister’s blunt talk a necessary boundary, or too cruel a cut?

This older sister’s clash with her clingy sibling is a raw tale of love tested by limits. Her call for less neediness, backed by Reddit’s nod to boundaries, aimed to free her life but left her sister feeling rejected and parents questioning her tact. As the rift lingers, one question looms: can they balance closeness and independence? What would you do with an overly attached sibling? Share your stories and weigh in on this heartfelt drama!
