well, Ishi, imo, you need to figure out your priorities. I think the main problem is that your top priority seems to be your education... and maybe your boyfriend seems ignored? so, what do you need to do is stop focusing on your education (consider dropping out of school) and focus on him... this guy deserves all your time and energy. he should be your only priority. forget about everything else.
and the fact that he blackmails you by telling you that he will tell your father about the true online love that you two share only shows how much he truly loves you. blackmail is the definitive sign of true love.
in conclusion, I stand by my original advice - he seems like a keeper. consider running away with him. you two will be so happy together. good luck. :)
