aitah for cutting off my hg of 7 years

context: me and this girl have been friends for 7 years. we grew up together really. she's done me wrong in the past multiple different times but i just decided to give her the benefit of the doubt multiple times about whatever happened mainly because i cared about this girl a lot. Recently another childhood friend died and she wasn't there for me because she was busy moving (not an issue) but that event got me thinking to what she really means to me. She's gone through around 3 different NASTY breakups and i was always there for her, even during my finals i'd talk to her to make sure she was okay and that she got some form of closure nonetheless
Since around 2024, all we have done is check on each other and update each other on our lives. usually it'll be that plus a bit of her telling me "ughhh i want a boyfriend" or the polar opposite which is "im a strong independent woman" and thats fine. My issue is the fact that the friendship is literally just that. Before 2024, i would always text first, try to engage conversations when i could and i'd just be left on read and delivered so i stopped texting first. since that time, we stopped talking a lot. She acts like this friendship means a lot to her but i really don't know if i want to believe her. The reason i question this is, aside from the constant being left on read (when i'd be left on read she'd always be on a game or listening to music + she'd text other people who are mutuals between me and her so i knew she wasn't really busy)
Recently i expressed my feelings about the friendship, how i don't like her leaving me on read, how we barely talk because I stopped texting first, how all we do is check in on each other (not really an issue for me, more of just the fact that its all we do as "friends") and then disappear for another 2-3 months, and more problems. She initially responded by just apologizing for everything and how she's "here for me" (her words), then saying that i probably just need a break from social media because im in a pretty bad mental state atm??(no correlation between my mental state and social media but i digress) then i got to the point which was just me asking "how do we move from here, is the friendship gonna remain stale forever, because its either i text first and u leave me on read and we dont talk, or you dont text me first unelss you need something" just for her to leave me on read again.
I gave her 2 weeks and still haven't gotten a response. So i just unadded her, can't bring my self to block her yet. I really dont know what to think of me or her in this situation because its just how she is, even though she said she'd fix the bad texting and the texting first part but to no avail. She texts other people first, even though apparently im her closest friend (according to her). so i really dont know what to think. It's not like i really want her to text me everyday. I just want to feel like im talking to my friend that i care for, the person who i grew up with, the person i almost got into a relationship w ffs. I don't want to feel like I'm catching up with an old friend—I want to feel like I'm talking to my friend of seven years. I care about her so fucking much, but I don't know whether the friendship we have is something I can continue accepting. she says that this matters more than anything and how she doesn't want to go through college without me, and yet i see no form of action to back up any of the nice things she has said about this friendship.
