I was going to say, what would worry me is when your DD starts graduate school at 18 or 19. By then, she's be financially semi-independent on a fellowship and there won't be much you could say or do to stop her from making choices she'd most likely regret later.

But you don't have to seriously worry about this for 3+ years. For now, it's wonderful to hear that she seems to be in a meaningful and healthy relationship. He's very lucky. smile
