My fiance and I dated through out college, about 1000 miles (roughly 17 hours drive) apart from each other. We went to high school together and had a bunch of mutual friends, though we weren't friends with each other. We started dating Thanksgiving break of our Freshman year in college. That was about 6 years ago.
Today, we're living together and getting married in 4 months.
He was the best support for me in the world. We didn't have any problems with friends outside of our relationship. He was in a fraternity, and I'm naturally pretty social. We talked every day, but we still lived our own lives (This is extremely important). At one point, he even studied abroad in Germany while I was in the US.
It can work out.
Think of it this way -- most relationships, long distance or not, will fail. How many people do you know married the first person they dated?
At the same time, don't give up on new experiences and new friends. Make sure you live in the present.
PM if you want to talk more
Good luck!
