Girls, What if he was being so nice to you, and caring about you, saying he likes you, and calling you all time, then you found he is dating someone?

If he knows what he's doing to you- leading you on, then he's quite messed up. He thinks he can have his cake & eat it, too. If you tell him you know about her, he'd likely tell you it's nothing serious, that you're better, etc.. Don't feed into this. Set boundaries, effective immediately. Don't get too comfortable with him. Move on, because he was never really there. Don't hurt yourself over something that was nothing.
I would laugh and call him a schmuck
