I started falling for a guy that might move far away... any advice?

Hey, I understand your problem and it may or may not please ya to hear this but I'm a dude and I wanna help you. I know you will be glad to hear that you are not alone and i have been in this situation before with a girl. What you do is you confess everything, not all at once but gradually. And if he is worth you liking him then he'll understand and open up to you too. What your aiming for is a meaningful talk about your feelings and for him to explain how he feels about the situation. After that it's up to you and him to work it out cos that's where I come out of the dilemma because I don't know you both. I hope this helps. Thanks for your time.
