Players claim to fall in love — QUICKLY. They give you the sense that they have been waiting and waiting and waiting  for someone just like you... and they tell you on the second date. They will start strong—calling often, texting even more often... and it plays right into someone's self-esteem. Then, once you have slept with them and/or shared your mutual feelings... it stops... and they leave you wondering: "What did I do wrong?" 

What to do: Be sure to see the signs of this trap. If they are pouring in to you (and your self-esteem) to such an extreme so soon, chances are it's not real. Granted, love-at-first-sight is a possibility... but if the love is right, it will be there weeks or months down the line.
