Firstly, tell him that he doesn't necessarily need to be the “strongest” man in the world,
that if he cries, you won't look down on him for it,
that you won't call him weak.
Tell him that he doesn't have to like sports, or fishing, or football, or any of the “mainstream” things that boys are “supposed” to like.
Let him know that liking art, or dancing, or singing or acting doesn't make him gay, doesn’t make him any less of a man, it just makes him who he is.
A human being.
And for goodness sakes, tell him that blue does not have to be his favorite color, than he can indulge in pink, or purple or even magenta!
And to the girl who take on the task, remember please, that it is not always the Knight who saves the Princess.
No, this time, the Princess may need to save the Knight.
Do not pour your problems onto him, rather, balance each other out.
Be a shoulder to cry on. A friend to be there. A love that never leaves.
Perhaps more than often, he'll lean on you. He'll cry to you, and squeeze you in agony, to the point where you can no longer breath.
You'll be his pillar, his center of life, the one who rises with him, and the one who falls with him.
Never forget this, for you are a Queen. And a good Queen takes care of all of her subjects, including the King.
And out of his agony, and out of his pain, your love will spring up like a flower.
And the exhaustion will be worth it in the end.
