Taking A Relationship to college

My freshman year i started talkin to a girl about 1 month before leaving for school. Thinking that i would be able to balance a relationship and school, plus the distance because she was still in HS at the time. But i found myself calling her about 3 weeks into school telling her that i didnt think we should continue because i found myself growing on people and i did not want to do anything to hurt her. basically i was not mature enough at the time to handle a long distance relationship. Now again as the new year comes around i have found me a special person and this time i feel as though i could go all over the world and still be faithfull to her. she is my other half, i would never do anything to hurt her and dont plan on breaking up with her anytime soon. If anyone else has had any relationship stories like this please feel free to share.
