Now im confused.... she can't get him out of her mind... yet when you told her your parents had set a date for your wedding she cried a lot. So who is she in love with you or him. It sounds like your dealing with a typical westernized, attention hungry girl, who wants to take things from others. The kind that has her eye on your plate when shes eating her own food. It doesn't seem like she is concerned with the fact that the other guy is married and your about to get married. As long as she gets what she needs. I understand that she wanted to get married to the other guy... but any normal self respecting girl would back away after he CHOOSE to get married to someone else. Who in their right mind wants to be the other woman? I think this is typical for her and I don't think it will make a difference if you are to cut off all relations and never speak to her again. She will just find another married man to run after. Some women want what they can't have!
Ughh disgusting... back away from her as quickly as you possibly can, regardless of whether you stay with your fiance or not!
