best friend, and we are in love with each other but I'm leaving the country

Ok so I have a man best friend since like 9 years ago and we are inseparable we tell each other everything, and we like each other since always but we have bad timing so we can't be together and last year I moved out of the country but we kissed before I left and that was like a kiss from a movie it was perfect. I came back for xmas and we have been hanging out in this kind of dates and all is perfect with him. But I'm going away again. I don't know if I should wait for him or just leave this the way it is and just be with him when I can, or just try to move on. I love him and is hard to just let it go.
