I am in a long distance relationship. My Girlfriend went to Smith in Massachusetts while I was in California. I now go to Columbus College of Art and Design in Ohio. I am going to tell you what it's like, since I have already done it.
There will be a few bumps along the road, but you have to cut some slack since you are so far apart from each other. My girlfriend and I are kind of already lax about the situation, for example, we don't view kissing as a form of cheating. We do, however, view sex or oral sex as a form of cheating. I know most people aren't as unconventional as we are, but if you think about it as just experimental college days.. it's not that bad (that sounds really bad).
Anyway, now that we are both in college, it's especially hard because there are all these new people, people you want to get to know, people that will wind up liking you and all that. You just have to know each other's boundries and be firm about them.
We both have web cams, so we can see each other as much as possible, and this includes instant messangers. We call each other all the time, and it's going alright. Just look forward to all your breaks and don't forget about how warm she is when you wake up in bed with her in the morning. Always remember before you go hooking up with someone that you have someone waiting for you. But don't be too hard on her if she messes up, unless she continues to.
I don't know.. if you have any questions, PM me, because I have already been through this, and I have been making it work and continue to do so.
