no younger then 12 and no older than 17.
It's a little too young yes but I know I had one when I was 12
At least a conversation. (about?)
You should tell the other girl and both break up with your boyfriend.
Smile a lot and hold his hand. He should get the message.
If he is her boyfriend, hopefully, she would like him.
no
A 12 year old girl is kind of young to have a boyfriend. It would be better 12 year old boys and girls work on just being friends first, until they are a bit older.
If you are a girl then yes maybe. But if you are a guy you should not be married If she has another boyfriend
yes you should

A girl should be attracted to her boyfriend. Nothing 'happens' except that they love each other.
