am i being too clingy and sensitive??

i have this very close friend. we've been friends for like 2yrs and half. she's literary the sweetest best friend i ever have. we always sticked together, ups and downs. but after 6months of being with her, she got herself a boyfriend without telling me(im not mad but suprised and dissapointed). but when she got she rarely hangs out with me and i understand it too but she hurts me(emotoinally, like randomly ignoring or not talking to me) sometimes when shes not in the mood bcuz of her bf. and then they broke up, i literally hate her ex bcuz he changed my shyla. i comforted her and stayed by her side for weeks then after couple of weeks of her break up, she got another man. im tweaking huhuhu. i hate it becuz when we hung out it feels like im talking to an empty shell bcuz shes always in her phone talking to her boy, and when we are talking, all she talks about is her boy. and when shes not in the mood bcuz of her boy, shes always moody, angry and doesnt talk to me. she only hangout with me if she and her bf had a fight. it feels like im a backburner and i hate myself for being jealous of her boyfriends. i hope she doesnt depend her life to hey boyfriends. she changed so much i feel like a trash for being like this. i wish we could be friends like how we are in the past
