My daughter is 25 and lives at home. She sometimes sleeps at her boyfriend's. They've been dating for about 3 months. He is 25 also. He treats her spectacularly....he takes her to dinner several times a week, brings her to his family outings, comes to our home and behaves respectfully to my husband and me. My husband likes him.

Bu, hubby always makes a fuss when my daughter says she's sleeping over at "Jim's". He says she's cheapening herself. I think he feels he needs to say that as a father. He is otherwise a gentle, loving father. What makes men act this way when it comes to their daughters?
