in a relationship but having feelings for another?

Hey… I have an amazing boyfriend whom I love so much! I am totally dedicated to him, and he’s everything to me. I have been with him for three months, but I’ve only seen him once since we began our relationship because he lives an hour away from me. We would talk on the phone every day until my parents found out. Now my parents and his parents are trying to keep us from contacting each other because they don’t think that now is the time for a relatioship. (I’m 17, and he’s 15.) Now the only way we really talk is online… I’m a freshman in college (even though I an only 17) and I recently met this really nice 24-year old guy. He is very nice and fun to be around, and lately I find myself attracted to him. I am positive that he likes me because he’s shown it in the way he treats me, even though he knows I have a boyfriend… Just today we went for a walk, and he sorta put his arm around me… I’m so confused! I love my boyfriend (Cody) so much, but why am I felling myself attracted to this other guy (Cory)??? (I know it’s weird that their names are to similar!) What should I do? And should I tell my boyfriend Cody about Cory??? Please help!
