Is it so uncommon to love someone without dating them?

I love a girl. I haven't seen her in 5 years. She is the girl of my dreams. I love her more than anyone else in my life. Beside my mum, dad and brother. Maybe 1 of my best friends. When I say I never dated her they say u don't love her. If I don't love her why am I tackling depression for the last nine months? I love u. I wish I did not have to move so far away. Parents made me. I wouldn't if I had a choice. I wish I told u I love you.
