Burner account cause friends know my main account 

Background, I'm currently a junior in high school, friend is a senior. We were real close friends for 3 years. This happened a couple of months ago, but a recent argument with someone else brought it up again and I've always been worried I was in the wrong. Now I have the tool of this sub. 

So me and her had an argument a few months back to which she blocked me for a petty reason (I already got judgement from others on that). A month goes by and I finally find I'm unblocked, ask her if she's still mad, and she says no. After this though, I have to initiate every single interaction, from talking to texting to spending time together (which she always declined). She didn't even say hello in the halls. Only on 2 occasions does she show any effort, once the day after I texted her where she came over and sat with me for the final 10 mins of a study hall we share and the week before Christmas break. 

She asked to spend time with me on the coming Saturday but I had to decline as we had plans with family from out of town and would be gone the whole day. So over the first few days of break she occasionally sends me memes when we're not having a conversation, and those we do have I initiated. 

Fast forward to the day after Christmas and she blows up on me (all through texting mind you) for never talking to her, never spending time with her, etc despite me always asking and texting nearly every other day. When I call her out on this, she responds with "well you could say hi once in a while" which rather confused me. 

Once we both calmed down after more arguing, I tell her that if she's not going to put in any effort then neither will I. She reads this and blocks me and it remains that way now. I've made no attempt to fix it this time. 

Which I why I come here. As I said, recent conversations brought this up again and I've had some people tell me to get into contact somehow and others say not to and I'm at a loss. I'm worried I didn't do the right thing, and am seeking more mature judgement. So, AITA for not trying to fix it this time? 

TL;DR friend gets mad at me for “not giving them enough attention” despite me initiating anything we do, blocks me when called out and given a choice
