<human>: Can you give me the gist of the text in a nutshell?

I'm a home schooled senior in high school, and I spend all of my free time volunteering, which generally doesn't give me an opportunity to talk to people my own age. On top of this, almost all my friends have moved away for college, so I'm left with no one I used to know either. To prevent myself from going insane, I joined a social network/dating site to find a few like minded individuals.

I've struck up several conversations that have lasted a week or so with girls that not only do I have a lot in common with, but really enjoy talking to as well. A couple of them I'd be interested in pursuing something more serious (I'm aware about the difficulties of long distance), but I'd rather not distance them if they don't share my sentiments. I'm just curious as to whether or not being straightforward would be the best route. 

Up until now I was planning on saying something along the lines of this;
"Hey, I really enjoy talking with you, and I'd like to see our friendship develop into something more. If not, I understand, and I'd still enjoy talking as just friends."

I just don't want to spend a month or two looking for something more without realizing it doesn't exist, when I could simply be enjoying a friendship. Any feedback and/or advice would be greatly appreciated, thanks!
<bot>: What's the best way to let a girl know I'd like to be more than just friends, but am more than happy to stay friends?
