Assuming it is, you really have no option at this point but to give it time. She may in the end decide that she doesn't want to be with you anymore and if that's her decision you're just going to have to deal with it. In the meantime, your options are to be patient with her and hope that she'll come around, or cut your losses and move on with your life. Pick one.
