I think this could be particularly difficult for you since you are a single parent and tremendous effort had to be placed in caring for your child. No doubt, there have been times that you have felt a special bond as well. It is natural and normal to feel a certain sense of separation twinges at this time. However, it is also a time of opportunity, both for you and your child. Ideally, someone she respects (other than yourself) will help her to comprehend that she has a responsible and respectful role to play as your daughter. For example, holidays with family should be honored whenever possible. However, try to also look at it as a chance for both of you to spread your wings. A chance for her to gain needed independence. And an opportunity for you to explore that part of you that has probably been buried for a long time. Look into your inner self to discover your likes, dislikes and interests. As you do this, any inappropriate behavior on her part will not sting as much. And as she sees your strength, she might actually be more inclined to hang around to see what you've got cooking.
