We all want to help each other & sometimes it can make a huge difference for the friend. BUT...
I would be wondering WHY the family is using Tough Love on her. Sounds very suspiciously like she may have an addiction. Whether to drugs, alcohol (I have a best friend in this category) or to the boyfriend or ratty lifestyle. If she is addicted - she has to learn to help herself and you can only suggest.
Frankly - if she was my guest and stayed out past my bedtime - I'd lead her to the door in the morning. Don't let her use you.
Sorry - but I've been down that road before. I will help people who really need the help. My brother is a real softie and he has taken in so many "users and abusers" at the cost of his own family. Try not to let that happen to you.
