I don't know what to do.

My son fell in love with a woman four years older. She has a divorce under her belt and a child.

My son is recently divorced, he wants to live life to the fullest, and he's taking care of her child. He takes the three of them for walks. On weekends he goes to pick her up from work and takes her home.

Why does he have an aunt four years older, don't he have young girls. How do you divorce them? I need specific ways and actions, what should I do?
