Should I end this friendship?

[klang]

I'm having all these memories of her, like when we went to the pool together in summers, had such a fun time pushing each other of the boat, telling each other stories, trolling people. But now since I moved she doesn't care. She always had better friends than me. When I went to her party it was terrible she completely ignored me, never said thank you for the gift, and looked at porn with her lesbian girlfriend. On Facebook she never leads the conversation, always mentions she has better friends than me. She lies that she can't go out, but on fb she posts pictures of her doing stuff with her gf. She said mean stuff to me and never apologized. I can't make new friends at my new school. But I feel I have to let go? It saddens me so much. She doesn't even trust me in fb but she does with her other friends. Her other friends don't even like me and say that I'm not they're real friend even though I went to school with them. I cried so much.
