My teenage daughter is out with her friends so I'm alone here tonight, but not lonely. Conventional wisdom suggests that a solitary life isn't healthy. Friends and close relationships help people live longer.
I haven't had a close friend since 1988. That friendship ended when I was df'd. I've had work acquaintances, but once they left the job, I didn't keep in touch. As a single mother, I had very little free time, and preferred to spend time with my daughter, and to make an occasional appearance at family events.
I'm content being alone and I do lots of stuff alone, though going to restaurants alone can be uncomfortable. If I meet people who I connect with, I would pursue friendships, but I'm not one who needs to socialize, so would not go out of my way to socialize with acquaintances. That seems to be more trouble than it's worth. I wonder if I'm missing a piece of the puzzle. Are there benefits to friendship I haven't considered? Why are friends important to you?
