I think it is a combination of 1, 2 & 3.He is in love, cant handle it and he is now upset coz he is jelouse and feels betrayed and dosent know what to do!
 
He also paritally admitted his feelings, so now he thinks it's time for HER to admit it too!
 
Being the "egotistic headcase" that he is... he can't stand to loose, so he is doing all this to break her and make her admit she has feelings for him too!... and yes I bet he has some fear of rejection too!
 
 
As far as he is concerned she HAS rejected him by agreeing to marry another man! SO he wants her to admit that she DOES care for him, and in doing so admitting she does not care for her fiancee!
