It was so perfect...and then it was over. Idk what to do.?

No offense, but it sounds like you guys did move quite fast. Why don't you try to slow it down a bit? Be there for him, if he needs it. Text him every once in a while, be friendly, but not too friendly. Keep in touch with him, and who knows, over time, something might happen. But if it doesn't, don't be hard on yourself. These things happen, people come and go. People who we think we're suppose to spend our life with, ulimately aren't our soul-mates sometimes. But we live and we learn, deal with our feelings, over-come the obstacles and move on. Never stop smiling.
