i was in a long distance relationship for almost four years. we kept in tough by phone, chat, and email. we ended up getting the same cell carrier with unlimited talk plans.
it was hard work to keep it going at firsdt, but very very rewarding. He was in my thoughts always. luckily we were able to see eachother 3 or 4 times a year for almost a week at a time. Good communication is key. anticipation is maddening. but in the end it was all worth it. Good luck you.
