How do I tell my best (guy) friend I might like him, but I'm not sure if he feels the same way ?

We just started really talking this year, but I think I like him. He's going out with a girl from a different city right now and I don't think it's going to last very long. I'm not really sure how to tell him, or find out if he feels the same. Any suggestions ? Thanks(:

I suggest you wait it out. Making a move now may force him to choose between you and this other girl. That's not an ideal situation to be in, whether he chooses you or her... You'll be "the other woman" and that status is hard to shake. Whether it's right or wrong, it puts you in a lower position in his mind and this will lead to problems before long. Wait until some time after they're broken up, and simply say that you like him and that you've liked him for a while. You'll find out quickly from there.
