Is my long distance relationship healthy when we scarcely talk and it seems that I'm the only one working 'ha?

My situation is complicated to say the least. First of all, I am with a man who is not entirely appropriate for me (according to friends and concerned parents) because of his age which is 7 years older than my 19 years. Second: It's long distance. It's been a month since I've seen him. We've been 'together' for approximately 3 months. I'm always used to being appreciated by a man but he seldom calls me before I call him, text, etc. We both have feelings for each other but I feel like I'm beined along by a guy that is taking 'my role'. I also feel like I'm working for this, like making all the effort with the calls. Despite how hurt my feelings are if he doesn't respond to my text for several hours, I'm bad at communicating my hurt feelings. I am also thinking that I'm closing myself to a lot of great guys where I live and whom I could have a real relationship instead of this half one. The situation is painful but he really does make me happy. I don't know if it's enough. or if this is healthy. Opinions? Break up or not?
