Do long distant relationships work out well.....?

i like this guy, he likes me. Nhe told me on accident when i asked him to tell me who liked me in the class and he said 'sorry, i cant trust u cuz people aways say they wont tell and they do. besides, i dont wanna tell u who i like) hahah anyways, tomoro his cousin made an event called 'i luff yew day' that happens tomorrow and i plan on tellin him. Thing is i moved to Mesa with my Tia and he lives in Yuma (where i use to live with my dad)... its like a 4 hour drive and the only way to talk to him is on facebook... i dont know though because i dont see how long distance can work out. If they ever do I havent heard of it... help please.? :D
