To think that people who say “they don’t need anyone” are just emotionally available and scared of commitment?

No.
I don't need anyone.
I'm not emotionally unavailable.
I'm not scared of commitment.
I don't keep complaining about being lonely.

Would I like someone? Yes, if it happens, but it's really not the be all and end all.

I've been married three times. Each time I've found my DH to be lacking in many areas (two of the marriages were ended by me, one by my DH). They either didn't see why they should demean themselves to clean, care for the kids, do general household admin, plan anything, take on jobs that were habitually 'mine' when I was ill or away... I loved them all in different ways, but am now single and mightily glad to not have to rely on someone who is incredibly likely to let me down.

It depends. People do vary quite a lot in what/how much they need from other people.
DH has a "best friend" that will get in touch every three months or two for a really long chat. Then nothing for ages.
We went on holiday with him once.
He used to get up really early, cycle to the village for croissants, leave breakfast out for us. Then fuck off on his own for the rest of the day. If you got up early you could catch him at it. It was like disturbing a timid forest creature.
He's not avoidant. He just has a very low need for human company.

Do you mean not needing anyone at all, or do you mean not needing a romantic partner?

I definitely don't need or want a romantic partner at the stage I'm at (recently divorced, long marriage) but I do need/want my kids, my friends, my parents, my siblings to be in my life. A romantic partner isn't by any means essential for my happiness, the last couple of years has proven that to me, and it's not because I'm damaged or in denial.

I'd rather be in no relationship than the wrong relationship. I was taken advantage of for years. So I am comfortable now knowing my boundaries. I don't need anyone- I want someone- but only the right someone.

I don't need anyone, I quite like some people's company though.
I am not lonely and I can get all the interaction I need through monor social interactions with strangers if necessary.
I live with DS and DH but if they aren't around I am quite happy on my own

What a strange post. Some people are just happy, even happier in some cases, being single. I don't need a someone and I am happily very independent, have been since I was a very small child. If the right someone was in the frame then I may well want them, but not need them.
If you flip what you've said on its head you could as easily argue that people who do have to be in relationships are needy and emotionally stunted as they have to have some of their needs met externally.

Well if you can understand that, then you can understand how independence and avoidance are two sides of the same coin.

And if you understand that, then you also understand why someone in that position would feel deeply, existentially lonely – and equally terrified of the vulnerability required to let people in.

Including, incidentally, the vulnerability it takes to lay that reality out on the table (where people will talk about it as 'just' avoidance).

And if you understand all of that... then what's the question?

Who complained about being lonely. 😊

As far as I can tell. I don't need any one, demonstrated by the fact, at 61, I've only lived with a partner for four years.

I have a happy teenager, a home (mortgage will be paid off this year), a pension, a career, functioning finances. Our home is like Piccadilly Circus some weekends. It would be hard to be lonely.

I've chosen not to have a relationship over the last 8 years, to protect my ds but that doesn't mean that I wouldn't enjoy an intimate relationship if it came along now DS is older. A man would have to add something to an already very happy life though, and that's quite a tall order.

Going through a break up at the moment (18 years married) and it was a wonder to me to be able to say the sentence ‘I don’t need anyone’. Every human being should be able to say it and no I’m not a hater of love or relationships (actually I write rom com!), but I think everyone should be an independent, they can be part of a team but capable of being on their own. Fair dues to people who didn’t need twenty years of a relationship to figure it out!

Is this about one particular person, rather than independent people in general?

I don’t want to be in a relationship. I’m ’fiercely independent’ (so much so that I’m not sure why it’s in speech marks like it’s sarcastic).

I’m not lonely though. And I don’t deny it’s at least in part due to past hurt.

No. I don't need anyone.

My choice to be with someone is that - a choice, a preference. It's not a need.

I think if you need to be with someone, you're probably not the sort of person to choose to be with.

What about those of us that were so neglected as kids, left alone for long periods, dealt with our own problems as there was no one to to sort them out. Learnt to cook, shop, wash clothes from a young age, responsible for your own personal safety, no one to go to when distressed and laid low for fear that social services, if they found out, would put you in a home.

So yeah, I don’t need anyone and never have and live my life accordingly and no, I don’t think I feel loneliness as others do because to me being alone is the norm.

However, it could make it difficult if I needed a counter-signatory for a passport 😜

In a lot of people, hyper independence is a response to childhood trauma. I am absolutely the sort of person who would say exactly that. It’s not that I don’t need anyone or am afraid of commitment (very happily married to Dh for 17 years, I do need him). But I was let down by so many people as a child and as an adult that it’s much safer to just sort yourself out.

I do wish I had more people in my life I could depend on, but not at the risk of getting hurt. I am tough and I get through stuff as needed. It isn’t really as simple as just changing or being less avoidant. It’s definitely a part of who I am and I can’t imagine it changing (though I wouldn’t say it’s something I’d generally complain about either). I know exactly how I am.

How is it any of your business?

Nope. I had a 41 year marriage. I am perfectly happy alone. Definitely don’t need anyone and am certainly not in denial, thanks. Take your amateur psychology elsewhere.

This depends on the 'person ' they don't need. Human connection is necessary, so it's important to have friends and/or family connection.

Not everyone needs to be in a relationship though, and that has nothing to do with being scared or emotionally avoidant. If they're complaining of loneliness, it may be that they do want a partner or maybe just need to find a purpose.

I don't want/ need a partner. I don't complain that I'm lonely though

I’m single, not exactly through choice but I’m perfectly happy alone and don’t need anyone. I’d absolutely love it if I met someone though.

iIt’s not something I think very much about.

This. In many cases it will stem from not having their needs met in childhood.
