I'm sorry that your daughter has been acting rude lately. I'm sure that once she moves out she is going to realize just how wonderful a mother you have been to her. I moved out when I was 18 to go to college in a different state. While I don't think I was ever rude or talked back to her (that was the one thing in the house my father wouldn't stand for!). I also also don't think I really appreciated her until I moved out. Now I'm 25 and I always brag about how wonderful my parents are and were to me when I was a kid living with them. I think I talk to her more now that I live far away then I did when I was actually living with them. I also love that now my mom hangs out with her friends, something she rarely did when I lived at home. It makes me happy when I call to talk to her and my dad tells me that she is out shopping or having lunch with her girlfriends.
