What’s going on?

PLEASE HELP MY ISSUE!! It gets long so I apologize for that but I (18F) have abandonment issues from my dad leaving me and emotionally abusing me at 7 to 10 years old and my best friend (20F) knows that. My brain just started to realize how wrong I was treated and how scared I am to lose people so I get attached and I'm also a big extrovert and big on feelings and my best friend is the opposite. It causes us to get into a lot of situations where we have to sit down and talk about what happened and what we are feeling. I've been told to always tell people your feelings so I always told her my feelings and a week ago I've noticed that she stopped talking to me and sent videos or only talked about what she wanted to talk about (over text) and completely ignoring my videos and my topics which is not like her but so I thought that she was being really rude and like she didn't care or something and I didn't want to play this guessing game so I told her that (not in those exact words) and after that text, which I sent 5 days ago, has been ignored. So I called to my mom and told her what happened and she said that maybe she was dealing with something at home so I felt bad for saying that and I told my best friend that if something was going on then she can tell me but I got ignored. And so I've been sending her mini paragraphs of little things, like telling her I care, or something of that sort. But then when I told a friend of both of ours, she suggested that maybe she needed a break because she wanted to be the best version of herself or something so I gave her that break from me. That was yesterday and today, I think she forgot that I am in charge of a public instagram account and she liked a post and so it confirmed that she was ignoring me. So I asked her if she could just tell me if she needs a break from me or if she doesn't want to be my best friend anymore and she has ignored that too! What does this mean and what should I do?
