Well...I do think it would be a good idea to give it a few days for both of you to difuse. You making a point not to call her (as she is your fiance) would be just playing games only making things worse. She likely might call first, but don't be above getting resolution. If you get married...to anyone...you are going to have to deal with situations like this and much worse. Whatever the issue is, she is probably needing you to understand and be there for her, but currently her pride is getting in the way because she probably knows her role in this hasn't helped.
