I would like anyone's advice about my current situation, It's a long story.

Well, this past summer I was working at this camp when I met this guy, he was a camper and about 6 months older than I am. Well, I spent so much time w/ him, the entire week that he was there I spent almost all of my time that I had off w/ him. He seemed like the perfect guy: was cute, a christian, nice, doesn't curse, and really sweet. So, when the week came to an end he asked for my phone # and email address.

So, then after I was done working at that camp, I went up and stayed w/ my grandparents in Tennessee for about a month. By this time he and I had emailed eachother a few times and I told him that I would be in Tennessee. Well, about the 2nd or 3rd week of me being there he called. We stayed on the phone for about an hour then hung up.

Well, when I got home I thought everything between him and I was fine and dandy, although I didn't know what kind of relationship he and I had, it's like we were more than friends but then we weren't b/f and g/f. Another thing that adds to this is the fact that he lives in a city about 3-4 hrs. from where I live.

So, about a week after school started back up I visited his website. And there I saw that this girl was writing things that well, sounded like she was his g/f. After I saw this I was mad mainly because he didn't tell me that he even had a g/f! So, about two months went by and I finally got the courage to ask him on aim about his g/f. The first thing that he replied was "awkward." So, basically he explained to me that he got his g/f the 2nd day of school, but didn't bother to tell me. Well, another month went by and I was trying to be his friend only. Well, one day that he and I were talking he asked me out, for this coming summer, I asked him what would his g/f think and he basically told me that he would leave her for me, and that he settled for 2nd best when he went out w/ her. I couldn't think of anything else to say but yes. Well, by this time it was November, and when December rolled around this kept on eating at me, so I wrote him an email and told him that I couldn't go out w/ him this summer because he had a g/f now and asked me out while still going out w/ her. So, on aim I was talking to him and he told me that he broke up w/ his g/f. All I could say was just for him to ignore the email that I wrote him.

Well, again this was eating at me because I kept on thinking if he did this to her, would he do it to me? And also I was thinking that would this last just the summer (he is going to get a job at the camp that I work at over the summer)? And I also was wondering about how I had to flat out ask him about his g/f rather than him telling me about her. So on December 15th I wrote him an email about all these things. Again we were on aim, and he told me that he would never do anything like that to me because he knew that I wouldn't go "retarded" like he said his ex-g/f did. Also he said that the only reason why he even got a g/f was because his friends were making fun of him for the fact that he didn't have one, and he said that they "wouldn't let it go". His answer about would this be a summer fling thing was that he would drive to where I live on weekends when he could, just as long as he was home before night. Which is a nice idea to entertain but not very likely.

So, what do you guys think? Should I go out w/ him this summer? If I do should it just be a fling and leave it at that, or should it be something more?

I would try it, but I would keep in mind about what he did to his other girlfriend and all that she had said to him on his webpage and all that he has said to you.
I would not be surprised if he dumps you for another girl this summer and all.
That's what I think, just keep in mind what has happened.
I wouldn't keep nagging him about what has happened and all. Chance are he's telling the true and there's nothing to worry about.
I would keep it in mind in case it starts to happen to you.
