Need help! How would u tell a guy you like him via Facebook?

[Victoria]

Hello all!
Just looking for some insight into this as I am considering telling this guy how I feel about him via FB.
Im not friends with him on there but I would like to msg him as he is leaving the same course as me
because he is finished and I wont see him again face to face.
What should I do and how do u think I should write this to him?
Any help/advice would b really appreciated, thanks!

More info; we have been friends for about 10 months during study and he had a gf when we met but they broke up shortly after. I have always felt this strong connection/attraction to him and I need to tell him how I feel
