You will know with time. If it's the real thing then it will last past two weeks. If not, it won't. If it goes beyond three months then there might be a chance of a loving relationship. A year and there's the possibility of real commitment. Also the "addicted" feeling that you are experiencing is normal in the first stages of both lust or love. That will go away, too, with time. See what's left over. If it's nothing, then it's infatuation. If there's something, well, there's some deeper feeling. Time, time. There's no way you can know now. You'll know later.
