AIO: ending a 10yr friendship

My best friend and I have been close for ten years. We used to talk multiple times a day and shared everything, even though we live on opposite sides of the globe.

Over the past couple of years, she’s started talking to me less. When it first started, it felt like nothing changed when she came back. But the last year, she disappears for a month at a time, only to come back with a brief “hi” before vanishing again.

I completely get that people have their own lives and things going on. I’m not expecting constant contact, but I don’t even know what’s going on in her life anymore. When I ask about her, she doesn’t really answer, and we don’t have meaningful conversations. It feels like she’s becoming a stranger, and maybe the friendship is just being held together by habit.

I’ve tried bringing this up gently, telling her I understand if she’s going through stuff and that I’m here for her whenever she wants to talk, and giving her space; however, she still doesn’t share. Eventually, I broke down and told her how much this distance and silence have been hurting me. She replied once saying she was sorry, that I seemed like I didn’t want to talk to her (even though I was the one trying to ask her about her life), that maybe I shouldn’t talk to her anymore, and that she would try to make an effort, but then she disappeared again.

Am I overreacting for feeling like I need to give up?
