My friend is ignoring me

Ive been friends with a girl since we were like 4 and now shes just ignoring me and acting like she cares i know she doesent .
Shes always telling me how busy she is and stuff while she scrolls on tiktok daily an sends me more then 22+ videos weekly (i dont know i dont check my msgs on tiktok frequently) I hate it she always tells me how her friends from her class are ignoring her are playinh games without her and once i came to her place ive told her about it and she made me go literally half of the city just for her to tell me that shes going with her friends at some drugstore (makeup shop ) i was really dissapointed she tells me how much she loves me and how im the only one who knows her problems but whenever i tell her mines she replies with a ":( " or "idk" but now shes leaving me on seen but lately i only sent her texts with what ive done at my grandmas place and funny silly stuff ans shes just leaving me on seen and shes not even busy i know her irl and what she does and she does not suffer of any mentally problem
Thanks for my online friends which took time for their own lives to talk with me and make me happy i really appreciate it <3 even tho they cant see it
I love you
