Q: Our 15-year-old daughter has told us she’s in love with a 20-year-old guy who is in the Army and intending to make the Army his career. We’ve met him, and he is extremely respectful and well-mannered, and has told us he’s in love with her. We’ve made it clear to both of them that for the time being at least, they may meet in our home, when we are home, and nowhere else.
