i’m deeply in love with my best friend he sees me as his sister and even though i told him how i feel i’m still his sister it’s so hard having to hide my feelings to protect our friendship and seeing him be happy with others is so hard all i want is for him to be happy he’s the only reason i’m still alive but e doesn’t know it everyone says he is toxic because he plays with my feelings we flirt a lot but then he switches and becomes cold and rude ik i shouldn’t get attached but i can’t help but love him and i don’t know what to do
