Confessing love...(I really need help with this)

So in few words, I loved my classmate for 3 years and I still love him now. I am now Senior and may not meet him again, I haven't told anyone that I love him, even my friends, because he has a girl he loves, who kind of could be considered a friend of mine. The study will end soon, I can confess to him now, but I live in a f**king third world country In which girls are just object. My parents would kill me if they knew I wanted to date someone, probably I will be mocked because I am in my country a girl who is in love, meaning that she is an easy-to-reach bitch.

anyway, I just feel more comfortable posting such a thing on this site. I really want to take anyone’s advice because I want to face reality. Even if he rejects me, it will be better than continuing in my life with these feelings.
