I agree with Mandy 15 is a hard age and to keep telling him its her loss.. He will be fine, make him understand that this is part of life.. The rest have given you good advice. I know it hurts us more when our children hurt... This will not be the first time.... he is a little to young to be dating he has his plenty of time ahead for that. Tell him he should just be friends with girls nothing more...
