What happened here, jerk behaviour??

Im new to the forum. One of the main reasons for joining, is that I need honest advice. this has been on my mind, and I need to either get it off my chest or Im going to go mad.
heres the story:
I recently met up with a guy friend I had been talking to over the internet. We have been talking to each other for the past 4 years. Im currently 18 and he's 21. We've talked on the phone,. numerous times, and exchanged pictures and all of that. So we finally decided to meet up. the plan was to spend the weekend with each other, since I live so far away. So I left my city and went to his, which is about 2 hours away. We finally did meet up and we went back to his dorm. We watched a couple of shows together and ended up making out/fooling around. We did this often, on the first day that we actually met. Coming very close to having sex, but we didnt. I decided it was not such a grand idea. What struck me as odd was he knew I was coming and yet did not make any solid plans for the weekend. That following morning we watched more television with each other, until he decided to take me on a tour of his school. We did that and came back. He then left me in his dorm room for quite some time, by myself, all alone to watching TV. When he finally did come back , he got a call from a friend of his ( a girl mind you) who lives in another school, not too far but far enough from his. We went to pick her up. So they could hang out. We picked her up, got something to eat and went to the mall. Basically all this time I felt like the third wheel. When we got back to her dorm, we watched bits of the red sox game, all the while, these two snuggled up to each other on the couch, while I sat by myself watching the game. When we got back from that expenditure, we came back to his dorm, his roomate, whom he shares a car with, asked what did we do that would use up so much mileage, he lied and told him that we had spent this really cool day together , doing all this really fun stuff. While in reality NONE of it occured. Then as expected, he left me alone again, as he talked to his neighbor for some odd thirty minutes, he came back, went into his room , went online (closed his door by the way) and left me in the living room by myself. So the weekend for me was becoming annoying. That following night, since we were sharing a bed, he slept at an remarkable distance from the previous night. The morning came and he had to go to class, and he kissed me goodbye. I was left AGAIN in his dorm room alone, and I had to get home. So I found my way out,. thanks to some other students that attend the school . I left and didnt leave a note although I thought of writing one. I made it to my cousins home that following night. I called him the following morning and left a message on his answering machine that I had arrived safely. I was expecting to talk to him online, since he is always the first to IM me when Im on. But in the past few days, Im getting the feeling that he has been avoiding me. I think maybe he was not into me that much, or he just wanted sex. I feel hurt and confused , because I really dont know what happened. the entire weekend felt like a waste And if it was, then I need to move on right?
