He is taken, but I think he still loves me. HELP.?

He loved me, and I loved him. He came within days of asking me out, but then he came back from Christmas break with a gf We were best friends after that, telling each other everything and tlking about love, relationships, EVERYTHING. Now I C him everyday and he always looks at me like he wants 2 kiss me. He calls me by the pet name he gave me. He always says that he doesnt know what he wants, and that he feels he cant trust his girlfriend. He says he also thinks it would be different with me because I am always the same Gracie..(his pet name for me). I need to know what he is thinking, because he is terrified of hurting his girlfriend. I need to get him to admit whether we are jus friends, whether he is terribly in love with me, or just whether he still feels something for me. He is literally the guy I feel I could marry, have kids with, and we have actually talked about all of that. Even while he was dating her, he mentioned that he thought of kissing me sometimes. What u think yahoo?
