Should I keep going with communication and expressing my feelings with him?

There's this guy that i totally like and i have known him for maybe 4 years at the most. and i talk to him on AIM and we really get along and u know im thinking this is such a nice like i mean loving family and the best grades and i always talk 2 the guy i totally love...but then i realize oh my god.......i forgot ...the guy i love lives in another state in virgina and im like well geez without love it kind of makes me really sad.So im thinking.... i should talk 2 him because ..HEY! i can't stop my feelings because just there and i can't control them but then i was like but i am aware that im just making myself sad which is never good and if u can help it then stay away from and i can because i could just stop talking 2 him but then i would get more sad cuz i wouldnt even be able to do what i can. so im confused and worried about making the wrong choice.But u know everyone says "follow your heart!!" but you know u shouldnt if its hurting u .PLEASE!!i need a second opinon.
