hi. it appears that you need to have a talk with your girlfriend. have her feelings for you changed? is there someone else? or, has she matured while you have not? it is very difficult to maintain a relationship when both people are in different countries.

what else are you doing with your time other than porn? do you work? do you go out with friends? go to school? it sounds like you might live an isolated life. to be a well-rounded person, you need interests other than sex. sports? reading? career? travel? it sounds like your life revolves around your girlfriend and nothing else, and that does not sound healthy and could be why she is keeping you at a distance.
