silently ditched by my bff

Last year, I’ve been silently ditched by my bff. Let’s start from the begining. We’ve known eachother since university and during that time she was in a toxic relationship with this guy who spent her money without telling her and treat her poorly. After their breakup we became closer and we started to hang out more. We share thoughts, ideas, fears and at some point, the same goals. We supported eachother during hard times in life and at the univerisity.
After graduating, she moved to a bigger city where her childhood bff lived. She told me once about her childhood bff that is a rising influencer and she told me that because of the little recognition she started to get, she is now pretty superficial and got on her nerves.
After some time I moved in the city too because i found a better job. I thought that if i moved there too, we would see eachother more often, but on the contrary I felt like she started to avoid me. Maybe it was only in my head, but she was posting regularly on social media that she was with her childhood bff.
She didnt called me like she used to, we didn’t talk like we used to. I tried to stop these feelings of being left on the side, and I did not said anything. At some point, she got a boyfriend. She never presented him to me. At first, she told me that she wasn’t ready to present him to other people. I respected her desicion, but her childhood friend met him at a gatering at her house.
She moved in with her boyfriend last year, and because she has hibrid work ( 1 day at the office and 4 days from home) she also left the city with him.
She told me that she will call when she will work at the office… she never did. She called her childhood friend instead.. and she also posted stories with her on instagram.
I mean.. I do not mind that she didn’t called me, because maybe she did not have enough time to meet me.. but she had time for her childhood bff…and at some point I wrote to her and I told her that I missed her and I want to spend some time with her.
She apologised and promise to call me next time. She did, we met, and during our conversation at some point she told me that ” some friendships are just over, without any reason”.
That sentence sticked with me. She continued to come at the office, she continued to spend time with her childhood friend and come to music concerts…
Since then, we didn’t saw eachother anymore. We didnt talk. I did not call her, no messages.. and nothing came from her either.
I am pretty frustrated because I really considered her to be a good and close friend to me and now, I can’t even stand to see her instagram picture.
She seems so fake to me now. I feel like I was treated like a shoulder on which she cried during her hard times and now I am just trown away.
It is hard for me, because I do not make friends easy… I speak like with 3 people besides my relatives.
