Most Helpful Girl
is he really someone worth fighting for? really think about it. you may think he is worth fighting for because he possesses so many good qualities. but everyone possesses both good and bad qualities. because that is what makes us human. but if the bad qualities over ride the good qualties or are causing you pain you must get rid of the bad from your life. unfortunately this means getting rid of the good too because you must get rid of the whole package to get rid of the bad.
the fact that he already is with someone else is a very bad thing which is probably causing you pain! someone who loves you doesn't move on that quickly! also what does it say about him! that just because of a mix up he jumps into someone elses arms! that is not a man worth fighting for! no one worth fighting for runs to someone else straight away!
if someone walks away from you then let them walk away. your destiny is not to be with someone who walks away from you ever!
this is just my opinion though! I don't really know what the mix up was about.
