What is appropriate in a long distance relationship?

Sorry if this is long:

I have just recently ended my 2.5 years relationship with my highschool boyfriend. We went to college and it ended for various reasons. When I first got to school I met a guy that I fell hard for(although I was still in my relationship) we did not cheat but there was mutual attraction and we became fast friends. He too had a girlfriend. Months into my relationship with this friend of mine I realized it was begining to ruin my relationship with my boyfriend..I had to make a choice. I decided to end it with my friend. I told him that I had feelings for him and that I couldn’t go on being his friend while with my boyfriend because it was going to ruin my relationship. I let him go. It was so painful for me because I think I really had fallen in love with him. I ran into him occasionally throughout the rest of the year, but I could always tell there was still something there- so I stayed away. I broke up with my boyfriend quite recently(2 weeks), for me though it has been over since I met this other guy. Two days after my break up I come to find out that my college friend and his girlfriend also broke up. I wrote him on facebook and he immediately texted me. We have been writing and talking ever since. Here is the dilema- we live three hours away and I am transferring from the university where we met. We have set a date to meet in July, and we are going to go from there. But is it possible to even make something like this work. And my big question is can we kiss on the first date…because it is long distance I feel that we should- we only have so many opportunities you know? But then part of me is like no that is not first date appropriate…So, in this situation what is appropriate… I’ve been given a second chance to make this work. How do I do it?
