Is today the day I cut her off?

I have a friend that I was very close to in high school. We graduated 8 years ago, and ever since then she’s never really reached out. I’ve tried to keep in contact and she’s always answered me but always prioritised other things in her life. It’s been 3 years now since we’ve last talked. We’re not in a bad place but I still cling to the hope that she’ll reach out again. Ask me to grab a coffee. Reconnect and talk about the old days. I’m tired of seeing her on instagram posting things because it reminds me of her and what I feel I’ve lost. I feel like it reopens a wound every time, but what if she’ll reach out soon? I’m so torn because I feel like I can’t move on from this friendship unless I just completely cut her off, but at the same time I’m scared to miss out if she ever contacts me again. Some advice would be helpful.
