Should I tell him??????????

Last weekend I had a little friend gathering and my friend and I both liked the same guy. At one moment he would flirt with me and sometimes flirt with her.

Later that evening our group went outside to chill while my friend and the guy I liked were left alone indoors. They got off (snogged, make out) with each other and I was crushed. People asked me if I liked him but I said no to not make things awkward since my frind and the guy I like got off with each other. I acted fine and happy but I was really hurt inside. They are having a long distance relationship (he lives a hours train journey from us). My question is should I facebook him telling him I like him? or is that just making thing complicated? and if I do what should I say?
