<p>When I was 20, I fell head over heels for a handsome man. It was serious, headed toward marriage. After a year of steady dating, my mother, who had a rule about not bringing boyfriends into the family, invited him to stay for a weekend.</p>
<p>When he left, my father took me aside and quietly said, "You cannot marry that man. He will never be faithful to you. He is too handsome. He has the kind of looks that attract too many women." I was indignant. That man adored me, but sure enough, a year later, I found a reason to pull away from him. We both went on to other loves. I fell in love with my husband two years later.</p>
<p>I talked to my first love about a year ago. He was getting married for the SIXTH time. He has no children of his own. </p>
<p>My dad was right. Even though I thought I wasn't listening to his fuddy duddy advice--my subconcious must have listened!</p>
<p>Give her a semester to make her own mistakes. If, by Christmas, the boyfriend is still lingering, then consider a frank word.</p>
<p>One reason not to allow quasi-married teenagers to sleep as a married couple is to avoid giving an endorsement of marriage. I live in a nation where teenagers routinely move into one another's homes to share childhood bedrooms. It's not a good look when the 17 or 19 year olds break up. Kids don't have the emotional maturity to cope with divorce.</p>
<p>We haven't had an older 'couple' visit yet, but for the youngsters, I say, find a stolen moment in your car, in the country, at the beach, at home when H and I are not in the house. There is plenty of time to be married, in my experience, ;) . No reason to rush into marital beds at 18.</p>
