It's whether you are content OP, or feel like there's something missing. I know someone through work who is always busy, got something planned for every single weekend with one of the many best friends she always keeps talking about; dinner parties, drinks out, activities, yet is one of the loneliest, most unfulfilled people I have ever met.
I used to have a much more active social life and a large(ish) friendship group of about 8 people but they have moved away so the dynamics have naturally changed. I also had a friendship group through my hobby but after having DS and lockdown hitting, it's just died down as I'm not able to meet up regularly.
I have a couple of close friends, who live locally, and someone from work I get on really well with and talk with most days but I wouldn't describe any of them as "best friends" although we have all been there for each other over the years one way or another and meet at least once a month (non work ones).
I do have a DH and a toddler who take up most of my weekends and whilst mostly I'm okay with that, I do sometimes miss the time when weekends were all about socialising. On the other hand, now I'm knackered by about 9pm every evening so if they were always messaging to meet, I'd probably be on here asking how to deal with over active friends who take the hint haha!
