That's all it is, I think. It's unbelievably beautiful what you did but she can't get in the mood if she's not in the mood. Think back to the bath - for her, I'm guessing she was cuddling with you then and that was as good as sex for her. Don't be surprised if she jumps you soon but she needs time. I can totally understand where she's coming from - lovely lover chips in around the house and wants some loving but the romantic overtures can't be returned at that moment. I'm too tired!
