If he has a girlfriend then, no, it is a bad idea no matter how much you like him. If he really likes you he would break up with her then go out with you. If you two are just gonna hang out like friends then he should tell her first so she won't think its cheating or something.
If you like him then go for it!
If a boy has a girlfriend then he is considered taking and you should leave him alone and later he may break up with his girlfriend.

Go to them and say "you crackhead".
You should do nothing. He is not good for you.
He probably has a girlfriend or does not see interest in you.
A boy at the age of ten can have a girlfriend. Dating is a whole other thing you should be in the presents of an adult.
11 or 12 is a good age for a girlfriend of boy who is 12Yo .
Just simply date the girl with out him knowing but take her somewhere the boy would not know about or expect his girlfriend to go
it's not that he "should" or he "shouldn't", if there is a boy who likes a girl and the girl likes him back, then why should they not be together?
Well if you want a girlfriend then go to mixed if not then go to all boy
She should give him a piece of her mind and LET IT GO.
