Hi Therlie,
I suggest you first finish your studies. By then it will be a couple years later. Then I suggest you can return to Cambodia and see him. I promise you, this guy will seem so much less attractive and enticing when you give it a few years. In the meantime, to break your addiction, I would slowly end the video chatting to once a week. Then next year to once a month.
Good Luck,
Inky
