Why would a man be (overly) friendly or flirty with a woman in front of his friends but avoid her otherwise?

The guy is very confident, flirts with attractive women (alone AND in front of others) but avoids me and his body language and facial expressions indicate that he dislikes me (sneering, purposely looking in another direction etc.). He tries to keep conversation short and acts tense or disinterested but around his friends starts being super smiley, making good eye contact with me.

For instance when I walked past him and his friend once he started grinning, desperately tried to make eye contact with me by turning his body in my direction and overly enthusiasticly shouted good moooorning at me even though he barely acknowledges I exist when he is alone. Another time he came way to close to me with his face and later that day stared me down without smiling while walking by when I talked to his friend. What is his problem?
