Friend has a history of ghosting me, But I want to make it better

My best friend I had known since middle school ghosted me around August of 2020 on my birthday. she came to visit for my birthday and I offered my place to stay. She showed up at night and left abruptly in the morning without a word after sleeping over. I didn’t hear from her until a couple days later and I tried to ask what happened. I noted that I was hurt that she left without letting me know, and she said her and her boyfriend were arguing so that’s why they left. I could tell she wasn’t really sorry about her actions and I didn’t know if it was the whole truth because she had ghosted me similarly in the past too. She stopped talking to me after that, but I still tried to reach out to her because she told me she had depression before and I knew her bf was verbally abusive. She just didn’t respond.

After several months, one day I saw a post on insta that she had gotten a cat and that the cat saved her life. I just felt very upset seeing this post knowing she was ignoring me. I decided to remove her as a friend on my socials but I left my phone number available in case she wanted to reach out.

Around 2022, I had a dream about her, and felt a lot of regret from removing her on my socials. I added her back and messaged her that I was immature for it and wanted to know if she still cared about our friendship. I just didn’t feel like cutting her off knowing that she was someone important in my life before. I didn’t get a response but she did add me back on socials.

She randomly messaged me this year in 2023, saying she thought of me often and she appreciated that I was the only friend who ever reached back out after everything she had gone through, She noted she moved across the country and was dating someone new, and in therapy. I decided to respond and asked if we could talk things through more as I wanted to have a better friendship with her whenever she was feeling ready and I’d appreciate understanding each other’s boundaries because I had just started therapy too. That was back in June and I didn’t get a response from her since.

I had a dream of her again but last night and woke up feeling sad about it. I mustered up the courage today to text her and told her that I am sending nothing but positive vibes and that I am still open for a chat.

I guess I know I shouldn’t have expectations or believe she is 100% the same friend I knew her to be before. I just don’t want to have a burned bridge. I also want some closure. When someone doesn’t respond you have no idea if you yourself did something wrong and I don’t want to be oblivious to it either. I’m not sure what to do to make myself feel better about the relationship. We don’t have to talk all the time, but I want the reassurance that I can reach out without being ignored, and I feel like it’s not a lot to ask for. How do I go about trying to remain as friends? Is it really a lost cause and should I just let it go?

TLDR: My friend has a history of ghosting me and I ended up ghosting her on socials as a result. I apologized two years later and she messaged me a year after that. But when I messaged her back this year about having more of a friendship, I got ghosted again. I want to be just basic friends at this point, but I don’t know how to go about it.
