Sharing Our Innermost Thoughts

So…in April I got a friend from my workspace, virtually. She sent me DM with a helpful suggestion for my blog posts and I was so astonished by her helping mentality and also I was going through mild depression and the days were quite messed up, suddenly her words made me feel so good. she was friendly and ready for a casual chat but I wasn’t (I was hurt ever since 2020 due to the betrayal of my only close friend). then after every day we came up something to talk about, then it was all about checking notifications but I was cautioning myself not to get close but then the thing b/w us grew, we listened to each other’s broken friendship stories and promised each other that we are not gonna hurt each other at any cause. after my past stuff I resumed writing poetry, she shared her composed music, we became close, shared photos and moments, mysteries, dreams, passion, etc. she also started opening herself to me and narrated her tale, I gave her support even when I was struggling inside. One day when my day was fucked up and asked her “can I share something” she said “maybe sometimes later” then after discussing the timing she said “she can’t hold any of my sad things because she is having a messy day” I understood that and moved on. As days passed we helped each other and at a point, her lack of interest in hearing my stuff made me regret sharing things with her and burdening her so then I asked sorry and she said she didn’t like the regretting part, and we had a pretty rough chat. I made a special video including poetry about her and poured my heart into it for her b’day and then sent her. she has promised to call many calls to discuss my matters but that never happened, I felt like it’s all about her and I felt lack of respect for me. after her b’day we never had a good conversation. she needs support so daily I send msgs to make her feel good but no reply even if she is there in online, I wish she openly tell me whether she wants to continue this friendship or if she is not interested she can tell that, I asked that but she said everything is fyn b/w us and she is absolutely fine. IDK what to do. what should I do?
