Is it a red flag if someone doesn't have any close friends?

[Brunocatmon]

I know everyone is different, im very outgoing, I have a lot of friends, more than a handful of who I would consider to be close friends then a few besties.

I'm in my 50's.

Would you consider it a red flag if a person in their 40's only had one close friend, and one

I thought exactly this when I read the opening post.

Maybe the person you have in mind does have friends - they simply choose not to introduce them to judgy acquaintances.

You haven’t said what this “ red flag”
actually means, OP???

I don't think OP necessarily mean that. It could also mean that she would want someone who also value friendships, who likes to spend time with a variety of people, who likes to go out and socialise a lot, who doesn't value masses of alone time etc. Mabe red flag isn't the correct term to use, I think it's more, would you worry about compatibility if you met someone who didn't value spending time with friends/didn't have friends.

It is and I am not sure why - at university making friends was as easy as walking. Now it seems incredibly difficult.

I wouldn't call it a red flag, but more just an indicator that we may not be compatible as friends. I know where you're coming from OP - I value friends and company quite highly and prefer to be in the company of others who do likewise.

I previously had dcs at home then work 60 hrs a week with days off to recover.
I also suffered panic attacks so too unreliable to meet up with people.
I've settled on a life with DH and my cats.
I love people but need alone time gardening and chilling out .
No red flags.
