Why oh why oh why are you wasting your life masturbating to some dude who will never be more than your cam buddy? You know if you let this guy go, stopped talking to him all together and rehabilitated yourself from the addiction of wanking with him then you'd be able to focus on a real life mate that you could touch and kiss and hug and spend days and nights together and do things with. You are addicted to this as if he was a cigarette. You can't quit smoking if you keep having a drag.
You're silly. As the Asdfg and smackie have already touched on, this man is either married or otherwise involved and you are his extra-carricular past time. Don't be a fool any longer. Do a fade on him or tell him outright you're finished, heal from your emotional connection being severed and then get busy looking for a man in your area. You're 30 so move onto something a little more solid than a whank partner who lives 1000's(?) of miles away for goodness sakes.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
