I'm confused

Ok. Me and this guy who is a good friend of mine have been hanging out a few times. We are really good friends. Anyways the 3rd time he came over he kissed me. Btw that was my first kiss (I'm 16) anyways we ended up making out. Then that happened the two times he came over after. The 2nd time he came over shit got physical as in he did things to me and I did it back (no sex) anyways after that he never really spoke to me at all. He did call me the next day and we spoke but not about what happened. Then the day after that (two days after he came over) he told me we should stop hooking up (I agreeed) but when I asked why he said he was talking to someone and it was getting pretty serious. For me it was out of the blue. Then he took me off snapchat as in blocked me. But told me someone was getting jealous but I didn't understand why they were getting jealous.

*BTW before we started hooking up we both agreed there were no feelings.

Questions:

1. Do you think he has feelings?

2. Did he use me?

3. Someone help me because I've never been in a relationship let alone this drama.
