I have a 20-y/o daughter, who lives at home still. Her best friend and she recently got into a physical fight. I don't know the details, but the friend called my husband at 5:30 in the morning, and I was lying right next to him. She told a bunch of lies (they both had apparently been drinking. Long story short-I feel like this girl is not a good friend. I cannot control who my daughter's friends are, but she is not welcome at our home, and I have asked my daughter not to bring her name up around us, as she caused major family fighting. She, however, tonight brought the girl home, even though the girl stayed out in the car. I feel my daughter is pushing the limits, and I feel I have not requested too much. My daughter thinks I should just get over it, but my instinct and experience so far has been that this "friend" has stepped over the line by "messing with my family". I don't generally dislike people, but when I do, it's because I've been giving the benefit of the doubt until there is no doubt anymore. How do I handle this?
