What do I do if my gf 18F uses reposts on tiktok or instagram to repost sad things when we argue instead of communicating it to me and also leaves me on seen for a day? (17M)

Title gives basic context but recently our relationship has been really rocky and we even had a breakup scare the past few weeks where she said “maybe we should break up” and I basically said things along the line of its your decision and if it’s what you really want then you can go. I really do love her and I want it to be her but recently were revisiting what happened now and a recent argument we had where she said these events have left her unable to trust me anymore and that she can’t lean on me anymore and that she doesn’t know me anymore (which she reposted a song about not knowing a person they loved anymore). I don’t want to paint her as the villain here and please give me all the shit you can where and when I’m doing something wrong. While although being left on seen and reposting and sometimes even removing reposts about us while keeping the other ones The argument that basically this most recent occurence happened after I left her hanging for a while on delivery because I was asleep and we are in different timezones for the time being as we are both on vacation. She got mad at that and my response even though I apologised and said I love you to her. She also reposted a video where it said her life would be better if there wasn’t an insecure loser draining her and although I still think it’s aimed towards me, she said it isn’t. We talked about our recent issues in which she said she doesn’t know where she stands anymore and she thinks I’m out of the relationship and that she doesn’t see me as someone she can lean on anymore. I hate to see that I can’t be the person she sees as safe anymore but I hate it even more that she’s hurting. But right now I just don’t know what to do. I know she’s hurting and I’m wondering if I should check back up on her despite being left on seen or if I should give her some time. But it really does hurt me to see that she removes reposts about us or has me decode what she feels via instagram or tiktok reposts leaving me feeling very discarded and anxious. Should we wait a couple days until we finally see each other in person again after 3 weeks of practically long distance after our vacation and talk about it?

TL;DR:
My (17M) girlfriend (18F) and I have been rocky since a recent breakup scare. During arguments, she reposts sad TikToks/Instagram stories instead of communicating with me, and leaves me on seen for a day or more. She says she can’t trust me anymore or lean on me, and that she doesn’t know me. I don’t want to blame her, but I also would rather her communicate to me directly rather than have me decode her reposts on social media
