AITA for blocking my best friend on everything after she said she didn't want to be my friend anymore?

My friend and I have been very close and at one point started dating. One day she told me that she needed some time to improve herself and broke up with me and told me we would get back together in a month. We never got back together but remained very close friends. We got into arguments every now and then and most of the time it was something I did, but we would always make up afterwards. Recently I felt like she was getting very distant so l asked her if she even wanted to be my friend anymore and she said yes. I try to ask why and she said that out relationship had been going downhill since the breakup, but during our friendship I always supported and respected her and was always there for her. She never once tried to help our relationship in any way and I was practically carrying it because she lacked the communication skills to improve at all. I always listened to her complain about her parents and people at school and the support I gave her always took a bit out of me. She also just had a lot of problems at home and was stressed out about grades and I was always there to help her and to be there for her. After she told me sort of why she did it I asked her if it even meant anything to her in the first place which she said it did. I messaged her after school and asked her why she didn't try to fix our relationship at all. I mentioned some of the other things l've done for her and she replied with "alright man" so I responded "that's it? Seriously?" And she blocked my number so l decided to block her number and also block her on everything I could think of. She was one of the most important people in my life and I cared about her so much and I guess she didn't feel the same for me. I want to forgive her and go back to the way it all was before but I know she won't apologize and I shouldn't forgive her if she doesn't. The only way I could be friends with her again is if she changes and actually does something to try to make up and help like I always did. So AITA?
