Just a quick theological point - the Bible says "judge not, so you won't be judged", but the literal translation of judging in that instance is determining someone's entrance into heaven or hell.
The Bible says stealing is a sin. If someone steals, they sin. If they commit adultery, the Bible (not me or you) say it's a sin. How is it judging to point that? Just sayin...
Now, for YOU, Kevin, stop worrying about the life she is living. You can't live it for her, you can't change her, you aren't responsible for her. My suggestion is this - the time you would normally spend thinking about the life she is living - turn that time into prayer for her, and see which is more effective. Worry or prayer?
