Well how old are you? How old is he? are you guys both in school? Obviously you guys aren't married....
Scientifc way: Sometimes a girl is attracted to a boy and they reproduct. Modern way: they banged the boobs off her.
you don't if you do, both the boy and the girl will hate you (but mostly the girl)
There is nothing you can do if he has a girlfriend.Before making a move on him you should consider how you would feel if a girl did that to your boyfriend.
there is a boy and a girl. there is a boy and a girl sitting under a tree since boy is singular (must refer to first noun first)
If he already has a girlfriend, likes this girl a lot, and they are comfortable together, then you should not be trying to get this guy away from her. It will only cause problems, mostly for you.
This should make it easier as you already know one another - simply ask him if he would like to go out sometime and take things from there.
A girl
the girl should do what she want to do, if you're in love faith shouldn't keep to lovers apart.
There's a 50% chance it will be a boy, and a 50% chance it will be a girl, even if you already had three boys.
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?
The girl should tell the boy how she feels, to see if the boy feels the same way as well.
You don't if he has a girl let him be and wait ...
