Am I a cheater? Player? And a mean best friend?

The answer to #1 would be no you are not a cheater since neither one are your boyfriend and a player will date lots of people and tell them that they only care for them its playing mind games.There is nothing wrong with having a crush on more than one boy its normal.As for your friend tell her that your doing what she asked incase it comes out from someone else but down play it a little, she does not need to know how much he is talking to you.Can you tell him she likes him?If you can do it if you think he will like her back then you just say that your friend likes him so your not interested in being friends.
