(I apologize in advance if this message is long or I ramble.I just want to get everything out for people to understand

So there's this guy at school that I've been interested in for about a month. I've talked to him, briefly, only once. But everytime we see each other, the eye contact is so instense. I've never felt anything like it before.
The bad thing is, I heard a rumour that he has a couple of girlfriends. Then I heard from someone else that he doesn't.
I was out last week, and I was dancing with my g/f's. He was also there, dancing with another girl, but my friend noticed that he remained quite close to our group, staring,and everytime the girl with him tried to get close, he pushed her away.
What does this all mean? Does it sound like he is attracted to me or was he trying to make me jealous? Should I just approach him on my own? Or should I listen to the heresay and forget about him? THANKS!
