If you really love this guy consider moving out there to be with him. The two of you together need to recognize that long distance relationships don't ultimately work out unless there is a concrete plan for when you'll be together. Since you two are at a crisis point right now, you need to make that plan soon. You need to cooperate on making a plan for being together, figure out the details of when and how, and then you both need to do it. Either that, or say goodbye to each other nicely as friends before something nastier happens like he cheats on you before he has the courage to break up with you.
Life requires big changes sometimes.
I had a relationship which already grow for 3 years. I know my partner for 9 years. But now our relationship is not alright. We still meet each other every day. Only that he seem to be very cold towards me now.
