Love or just an infatuation

I saw a girl…she was very pretty and sexy too. I was very much attracted towards her. More clearly, I was infatuated by her looks. Believe me when I say - I know for real, looks can be deceiving but yet, her beauty pulled me towards her and after few more meetings, I figured out that I was madly in love with her. Just like in movies, I was willing to kill or even die for her or something like that.
Well, few days back I saw another girl …. more beautiful than the one I saw before and I was attracted towards her now. This time I am perplexed, whom shall I go after now, which one is love and which one infatuation.
