Sorry this is going to be a long rant/vent 

I've posted about her before, so this might seem a bit redundant since I'm asking a similar question. We mostly only text these days (although recently she told me she needed a break from me and I agreed) and it used to be a thing where we called afterschool everyday but it's stopped as she recently made a new set of close online friends. This has been the main reason for our conflicts and I wish it didn't affect me as much as it does/did. She's essentially online all the time, talking to them. I said I wanted to meet them since the group had people I'm friends with irl too and she eventually let me join the Discord server. I did, I got along with these people because they're genuinely nice but she kicked me out later on for unknown reasons. I pushed on about it (wish I didn't) in an argument that started off unrelated and she eventually confessed she wasn't comfortable with me being friends with them because she wanted to keep them for herself. I told her that was okay, because it is okay and it's perfectly normal but it doesn't stop my brain from interpreting her as some selfish friend hoarder. Like, she knows that she's the only one I talk to online really and that a lot of the times I'm very lonely. Then again, I'm not exactly a great person to be around with for long periods and I guess she wants a break from me? 
She's admitted that she prioritises these new friends over me and I don't know, it fucks me up? I really just want to be a fucking normal friend and I want to go back to how it was a year ago. Everytime I bring up her new friends or mention how she barely speaks to me anymore it only pushes her further away.

 On Tuesday she called me and told me that we should distance ourselves, possibly catch up at the end of the week. The premise of only talking to her one day of the week somehow hurts more than completely cutting her off. I told her that, and I haven't talked to her since. I also told her that she can reach out to me if she wants to talk again and I won't contact her at all unless she talks first. I wish I didn't say that because I miss her a lot. I miss having a friend and short connections over reddit aren't really the equivalent. I want to reach out even if it's only been 3 days. 

I want to try and change my toxic behaviour. I want to be able to make promises and keep them. I don't know if I should stay away from someone I've known for 5 years. Someone who is the only friend I have that I've opened up to about my BPD. She said she'll always be there, if I really needed her. I know I've said things that have really scared her. I don't want to make someone I love cry. I wish it was January, 2019, where we were okay and I wasn't fucked up after one of my friends passed away that october. 

Feel free to give advice :)
