I’ve always had 2-3 close IRL girlfriends, and a boyfriend (or now husband). I have many online friends here on PC.
I’ve ended relationships (it was mutual) with three really close friends. This bothers me a bit, while it probably doesn’t bother them at all. One was a childhood friend who fell out of contact with me. I didn’t nurture it and neither did she. Why not?

Another was a best friend from early childhood until after college. There wasn’t really a falling out. It was more again, just going separate ways and maybe not liking each other anymore? The other was a lifelong friend who turned into a frenemy. I think she has major issues, and she thinks I do.
My current friends are a mutual friend of the ‘frenemy’, who I grew up with. We lost contact for our whole lives of raising kids, until recent reconnection. We talk nearly every day, but she never wants to get together, even though I am willing to drive to see her.

it’s a kind, supportive, loving friendship, so I’m confused. The other I have known for around ten years. We do things together as couples and I have done things just together with she and I. It’s a very good relationship all around. Both friends are of similar backgrounds to me. We relate.
