High school mess up

Um Idk what to do anymore I'll explain this girl I almost never talked to at school or at all in fact messaged me on new years ok and needless to say she saved my life and she's so pretty and so amazing in every way I could not believe a girl like her even talked to me I fell for her she's been unhappy lately and told me she really likes my best friend I saw this as a opportunity to try and make her happy so I talked to him and now they are dating and at first I was happy but now it's killing me seeing her with my best friend taking about him like I wish she would me the bad thing is they both know how I feel about her and I told them it was fine that I don't care I lied of course but I did not want my hopeless love messing up her life Idk what to do anymore I'm just so heart broken over this people say you never truly get over your first love I just wished she'd give me a chance

Get around some positive people your best friend would not go there knowing how you felt had he had your best interests at heart like a best friend should.x
