well, maybe she truly hasnt been in the mood.. im in the mood 24/7 so i cant really say anything about that.. but maybe shes just been busy or preoccupied with work or school or whatever else she is involved in.

*idea* why dont you take her out to a nice dinner.. or make her a dinner at home with candles on the table.. just something romantic.. maybe shes feeling down, and that is definetly a good way to cheer her up
