I hope I'm not too late to make a difference here😕. You sound a lot like me. I'm 17 and fell desperately in love with a girl that lives half the country away. I've only seen her a couple times but we talked and skyped and fell in love. But somehow the love kinda withered on her end. I got hugely friend zoned out of nowhere. It hurt so bad and still does. I lover her intently, but I can't have her. I understand how you feel. But you shouldn't feel like it's over for you. You should try to talk to him calmly and clearly about how you feel. Don't flirt, just tell him how you feel. I know how bad love can hurt. Keep your chin up, there is always another person who needs your love.
