I have custody over a 15 yr old girl (no she isnt mine lol, i just take care of her)

She has newly informed me that she now has a boyfriend....

I think it is ridiculous that she is dating at 15, especially when i read the msn archive and see things like 'im so happy i have you, you are the only one who understands me' and she always puts hearts around his name-ypical puppy love. However, i don't think she should be dating at 15

whats everyone else's opinion on this matter please???
