I'm 39 and don't really have any close friends that live near to me.
I have a couple of old friends from uni I see once a year or so, a few mum acquaintances that live nearby and people I'll casually chat to at gym etc
Most of the time I'm OK with this setup. I don't really have time for a social life anyway. I have a busy job and do condensed hours, 5 days in 4,plus a young DC and DH so weekends are often about family time, visiting family, with the odd gym class here and there.
Now and again, I do wonder why I don't have close friends and beat myself up about it. I had various 10 years ago but they all feel away due to moving/ me getting more boundaries and being pickier/ lives diverging
I've made an effort to join gym, be chatty with other mums but I just don't want to force anything
