relationship problems...

My bofriend and I have been dating for 2 years I'm 17 and he's 19 and we never really have sex (we live together) he never kisses me or compliments me etc , he lacks the little things that makes a girl feel loved and it's getting to the point where at night when he falls asleep I just cry because I feel so unwanted and ugly practically like he never touches me , should I be concerned ... I don't have any friends because we travel Bc he is a pipeliner . I am just depressed and my last option is to ask y'all ladies ... any opinions???
