women only, help me (m) what to do here.

so i'm going to not really make this too long of a read, if i'm able to that is. me (m) and a (f) used to be long distance. for a couple months we haven't been together. so a couple of times we just had a couple arguments/misunderstandings/difficulty communicating. (we both sometimes misunderstand each other or assume things, i recently a week ago talked with her about having to ask questions rather than assuming) we agreed on that. so a week ago or so, we started talking again. in short she first said she needed to focus on working on herself, which i do understand. and well, that she needed space. i respect that. but the problem is, i am an overthinker. so she has not been online for 3 days, but when i sent her a video, the ticks showed blue. but when leaving and re-entering the chat, it went grey again. this is what i dont understand either, help me out here. did she mark it as seen or is this a glitch in the app? well anyways, today i texted her something along the lines of "you can just say if you need space, but i tell you when i go, and you just dissapear, i might stop reaching out, i'm not leaving but you have to reach out first now, i'm getting hestitant, but i'm here if you need me, i do hope you text me back, i dont know if you are ignoring me or if something happened to you" 4 days ago, she did say she won't answer all the time, but that it doesn't mean we can't talk. and if she agrees to getting better at communication, then why would she just dissapear like that? women, explain to me wtf this means😅 i know she is a very caring and loving person tho, and she struggles. so i dont think she is trying to hurt me on purpose. i just wonder, did she see that video or was it a glitch. ? and do you think i should expect her to eventually text me, or should i stop wasting my time? she did say, mby 5 days ago, that she does see us getting back together. we also did discuss having to fix problems in another way, and be better at communication. and i want that. i try not to text too much but i've got adhd and overthinking which is a really bad combination along with anxiety. so, what do i do now? i have managed tho, to only for the past 3 days, send one text every night. nothing more. well, what do i do, and is that video thing a glitch?
