Relationship Question!?

ok i was talking to this 1 brother of Omega Psi Phi fraternity. We were cool he used to come over and we watch movies, I warm him food up and such. He spent the night a couple of time. No , kissing or physical contact. All of a sudden I was thinking he was using me. He only called me or text me when he was hungry or anything in that such. His excuse is "im busy, i have 2 jobs a school". ok i stopped communication with him. So then I went to the club and started dancing with another brother of Omega Psi Phi and I didnt knw he was one until I asked one of my buddies which is his frat brother and he said yeah he was a Que. So then we talked over the phone for about a week and a half. He finally came over and we chilled, laughed, played, watched movies. I really like him but Im afraid that this is a mistake because I was hanging with his frat brother and all but we DID NOT HAVE ANY PHYSICAL CONTACT. So should I continue with his frat brother or leave him alone?
