Should I continue trying for a close friendship?

U I started dating a guy I'll call A for simplicity's sake, last February, and my best friend G got jealous, but was still supportive. A few months after I got into that relationship,G gave me a letter asking for space, because of her personal issues (she made it clear I had done nothing wrong). Between that, and my own issues, we started to drift apart, but never had a fight or anything. Right after I broke up with my now ex in November (she didn't know about that because we had stopped talking, and the relationship + breakup weren't well known, so no one would have told her), she got into a relationship. Now, a couple months ago,her relationship ended, and I think she has a new best friend now. It still hurts sometimes, but I've learned to deal with my jealousy in a relatively healthy way. Things are still awkward between us, but I try to make the best of it. In May, we were in a play together (we're both actors), and I came to the conclusion that she doesn't seem to hate me, so that's nice. She starts small talk convos from time to time, responds to things I say in group conversations, occasionally responds to my texts, (byut never texts first and often ghosts )nd consistently asks me for snacks (She's been doing that for years, so it's comforting). It was still painful, because I'm lowkey in love with her (she doesn't know) but I was alright with that.

The problem is, once we were interacting a bit more, it was easier to see through her lies and fake smiles. As much as she tried to hide it, I knew she wasn't okay, but there was nothing I could do about it, especially  when everyone else seemed to think she was fine. Then, during the May show run, her character had to cry every night, and while every other actor just fake cried on stage, she'd sob before, during, and after those scenes, real tears and all. One of those times, she came off stage to where I was manning the concession stand. I thought she was going to buy something at first, but then she started talking to me. She said she felt like she owed me an apology, and that this last year has been hell. I said something along the lines of I know, and I'm sorry too, then we hugged. A month later, it was her birthday, and I dropped the gifts I planned to give her last year (before our plans fell through), off at her door, without letting her know my plans. I also included a note, similar to one she gave me about a year ago, thanking her for asking for space back then, saying sorry in more detail , and reminding her I'm here if she ever needs a friend. I said my phone was broken in the note, and included my email instead, but she texted me (I saw it a week later when my phone started to work), so I don't know if she even read the note.  Now I don't know what to do, because we're probably going to see each other a lot when school starts up again, and have to work together, but I don't really know where I stand with her. I feel like she's given some mixed signals, so I don't want to bother her if the friendship is truly done, but I don't want to give up if there's still a chance. Any advice?
