I met this one boy, after a while of texting we went on a date. Dinner. Second date I had him over for dinner which we prepared together. He came over the next night again and we had dinner and drinks. We had mind blowing sex, this went on for a week straight and we felt strongly for each other. Then I found out I had to go to NY but didn't really know how long I was going to stay there. So I left and we kept contact everyday (sending pics, nightly recap of day) he then told me he had met someone and went on a date but felt he couldn't stop thinking about me and had made a mistake. We weren't official at any point in our relationship and I told him it was fine. (I was also meeting guys. ) I recently came back home and saw him for coffee a few times but I kinda expected for things to go back the way they were. I slept over his house a few days ago(nothing happened although I know he wanted it to) but I did kiss him in the morning. He has been really distant and hasn't contacted me for days which is not in his personality. He's been this way since I came back. I just want to know what is going on, I am really confused about this situation. What should I do. And no, I haven't contacted him either cause I've been the one initiating our conversations and I feel as though if he wants to see me he will call/text/or come by. Any opinions on this will be greatly appreciated.

Update: He sent me a text last night aroung 12 midnight "Boo. Too busy for our party, uh?" I didn't see the message till probably around 2am. Responded with" I hope you're having fun" nothing else.
