They deserve to go through hell before getting to date your daughter. Don’t deprive them of this right of passage.
Talk to them about:
- Loss (of the budding friendship they value today)
- Love (which has nothing to do with what they see from Hollywood)
- Leadership (they were born male – deal with it)

The life-long love of two people for each other is a gift from God. To the degree that they are like Him, they will love each other sacrificially and continue to grow in their ability to love. This love extends outward – first to each other, then their children, then to other family members, friends, and the world at large.
After love for God Himself, a spouse should be completely sold out — “all in” as they say — toward the well-being of their life partner. See Love.
