Helplessly In Love With My Best Friend

“All my life I have been in love with my best friend, but he only sees me as a friend. I want to leave the friend's zone so bad, but I am Scared that telling him how I truly feel, might have an effect on our relationship as friends. I watch him date different girls and it always end badly because they really do not know him and he forces me to have a life by dating other guys, but somehow, I feel the way I am hiding my feelings from him and scared of losing him if the truth comes out is the same way he is also scared, of telling me how he truely feels. Should I tell him?”
