Need friends but not that one

I typed a novel and 7cups just deleted it so maybe I'll try to be more succinct

1. I'm living the adult life, I have a long term partner I love, but I need to "find my tribe" because I'm lonely and need that sweet sweet friend group support.

2. One of my old friends, who always sorta overstepped my boundaries, now gives me anxiety, and represents a hunk of my life I want to leave to nostalgia, keeps trying to talk to me. Like I'd be fine if she just stayed socially passive like the rest of our shared old friend group that meets up like twice a year, but it feels like she's trying to stay in my face. I also realized a chunk of our friendship was because of convenience, sounds awful but you know we all do it.

I guess I'm just looking for advice on the situation? I'm stressed and tired and just want to be happy.
