Love Problems?

No body's fault. He is partying but may not be happy either. He can't accept you as his friend was rejected by you. I think his behavior is justifiable. You can have a matured conversation wit the guy who you like, tell him how you feel and why you said no to his friend. You can tell him that you could have said yes to his friend for time p but you didn't do that and that you didn't misuse anyone. Even after all this the chances are not too great but atleast he will think good things about you. Its difficult put yourself in the same situation you having to chose between your best friend and a boy who likes you.
